DON'T SAY IT ISN'T BECAUSE IT'S A FACT.
THE WEBSITE IS AT THE BOTTOM. 
Strange as it may seem, glass is a liquid. How can this be? It is surely a brittle transparent solid? But no, as surely as a dolphin is not a fish, glass is not solid but liquid. To understand this, it's important to see that liquids aren't all the same as each other. (But hang on a bit, this can't be right, can it? Note: Please read the whole page before passing comment on this!) Water, the obvious typical liquid which others are compared against, isn't the same as liquid nitrogen or liquid metal mercury. More notably in the strange business about glass, syrup and treacle are notably different to water. It's much more difficult to stir treacle. This property of being difficult to stir is known scientifically as Viscosity. Some liquids have a very high viscosity and flow so slowly that by the time a can of liquid falls over there is time to pick it up before it spills! The ultimate example of a high viscosity liquid is glass. The viscosity of glass is so high that even though it's a liquid it looks like a solid. But if you could see glass from the comfy seat of a time machine, you'd see glass flow like syrup.
If this seems too strange to be true, take a look at reflections in window panes and glass on framed paintings that are very old. Glass that's a hundred years old is rippled. Two hundred year old glass has a distinctively undulating surface. You can use this knowledge to tell how old some antiques are, and how old the glass in the windows are on some buildings.
Taken to its extreme, if you had a large cup made of stone which could be left undisturbed, if you put pieces of smashed glass into the cup and left it there, if you could come back in a million years, you'd find the glass had flowed and taken a form like ice frozen from liquid water.

Glass is a solid. Its a fact.

did you even care to read.
Skimmed. Saw a link from a sketchy, unknown source. Then I walked into the living room, pulled up the blinds, and touched the glass. To my amazement my hand was not wet, my hand didnt go through the glass, and the glass was not phased by me touching it.

you know, no one has ever told you that glass is a liquid so you asume that it's a solid. its a liquid with a very high viscosity. you know what, whatever know one believes me.
it does not have to be like water to be a liquid. what about sap from a tree thats liquid with high viscosity. do you even know what viscosity is?
Let me guess. You were bored and ran across this website, some random tidbit, and now you are the shit and have 20 years of experience and a degree in bio-chemisty, mathematics, and various sciences.
By claiming glass is not a solid and infact a liquid, then you are going against everything everybody has learned in their life about this subject. Since you believe this, you should come in business with me, im selling snake oil in a few weeks, I just need to find a website to convince people that its not bullshit and really does cure disease.

I actually think its a solid. The main difference between the 3 states is the molecular interaction. Air with unrestricted movement, liquid with somewhat restricted movement, and solid so packed that the material takes on a shape.
What appears to be a melting effect in glass over a few hundred years is actually an effect that happens in all solids as they slowly are pulled down by gravity. However, the defining feature of a solid is that you are able to shape and use them as a tool without it dissipating.
What a load of Troddle....
Glass is a type of non-crystalline or amorphous solid. By traditional convention the term glass is reserved for an amorphous solid which has been formed by quenching a glass forming liquid (or melt) through its glass transition temperature sufficiently quickly that a regular crystal lattice cannot form.[1][2][3][4] However, amorphous solids may be formed by methods other than melt quenching, such as ion implantation or the sol-gel method, and since they exhibit the same disordered atomic structure the terms amorphous solid, glass and non-crystalline solid are often regarded as synonyms.
Glass in the common sense contains silica as the main component and glass former, but silica-free glasses also exist.[5]
Behavior of antique glass
The observation that old windows are often thicker at the bottom than at the top is often offered as supporting evidence for the view that glass flows over a matter of centuries. It is then assumed that the glass was once uniform, but has flowed to its new shape, which is a property of liquid. The likely source of this unfounded belief is that when panes of glass were commonly made by glassblowers, the technique used was to spin molten glass so as to create a round, mostly flat and even plate (the Crown glass process, described above). This plate was then cut to fit a window. The pieces were not, however, absolutely flat; the edges of the disk would be thicker because of centripetal force relaxation. When actually installed in a window frame, the glass would be placed thicker side down for the sake of stability and visual sparkle.[20] Occasionally such glass has been found thinner side down or on either side of the windows edge, as would be caused by carelessness at the time of installation.
Mass production of glass window panes in the early twentieth century caused a similar effect. In glass factories, molten glass was poured onto a large cooling table and allowed to spread. The resulting glass is thicker at the location of the pour, located at the center of the large sheet. These sheets were cut into smaller window panes with nonuniform thickness. Modern glass intended for windows is produced as float glass and is very uniform in thickness.
Several other points exemplify the misconception of the 'cathedral glass' theory:
Some glasses have a glass transition temperature close to or below room temperature. The behaviour of a material that has a glass transition close to room temperature depends upon the timescale during which the material is manipulated. If the material is hit it may break like a solid glass, however if the material is left on a table for a week it may flow like a liquid. This simply means that for the fast timescale its transition temperature is above room temperature, but for the slow one it is below. The shift in temperature with timescale is not very large however as indicated by the transition of polypropylene glycol of -72 °C and -71 °C over different timescales. [13] To observe window glass flowing as liquid at room temperature we would have to wait a much longer time than the universe exists. Therefore it is safe to consider a glass a solid far enough below its transition temperature: Cathedral glass does not flow because its glass transition temperature is many hundreds of degrees above room temperature. Close to this temperature there are interesting time-dependent properties. One of these is known as aging. Many polymers that we use in daily life such as rubber, polystyrene and polypropylene are in a glassy state but they are not too far below their glass transition temperature. Their mechanical properties may well change over time and this is serious concern when applying these materials in construction.
Glass is made from Silicon and Silicon is a ROCK.

You are both right. Glass can be considered a high viscosity liquid due to the peculiar characteristics and behavior (or lack thereof) during first order of thermodynamic phase transition, however it is usually considered an amorphous solid.

Once again the reason Church glass Droops at the bottom is due to the centrifugal forces used to make a pane of glass in those days. Try reading peoples replies as this was already explained.

In medieval times to make a pane of glass they would first of all make a blob of molten glass and drop it on a flat board which was then spun very fast to stretch out the glass this would make a rough disk shape. The when cooled a square was cut out from the centre which was thinnest and clearest ]. This was how a pane of glass was made and because of the disk shape of the glass before it was cut into a square the edges will be thicker and more bulged out.
This is known because of..
A. people in Europe still make glass this way.
B. It is clearly illustrated in paintings depicting places like Cathedrals being constructed.

That comment has made no sense at all?
Anyway here is an interesting article on old glass pane making that also helps to explain the irregular thickness of Church windows.

Dont worry ill pray for you real hard, everything will be fine, just give it time. The first step to curing anything is admitting you are wrong and/or you have a problem. Just admit you believed some random asshole online about something he thought about when he was high as hell and just felt like writing about it later on, its ok atleast he only scammed you of your dignity and luckily not your money.
OP is not exactly wrong, determining the state of glass is not simple matter, everything doesnt have to be black or white. However the article he pasted is clearly written in the omg exasperrated sensation style and without showing the other side of the coin.

glass is a solid. Not a liquid. It comes from heat blasting common sand until it melts and "rehardens" into a more uniform and smoother surface.
Those ripple effects that crazy website talks about it isnt from instability from within a liquid environment, but from the ancient ways glass was blown to form into window panes and that myth has already been solved. If glass was as liquidfied as they suggest, then roman glass (much older than cathedrals) would have been severly altered; which isn't the case.
Your new here so I'll be gentile....... don't believe any website you run across and make sure you look at the other websites too.
People who have to create conspiracy and hate threads to further a cause lacks in intellectual comprehension of diversity.
Saying glass is a liquid after it is cooled is a stupid statement. It doesn't take a rocket scientist to know glass goes from a liquid state when being made to a cooled state of being a solid.
It is sometimes said that glass in very old churches is thicker at the bottom than at the top because glass is a liquid, and so over several centuries it has flowed towards the bottom. This is not true. In Mediaeval times panes of glass were often made by the Crown glass process. A lump of molten glass was rolled, blown, expanded, flattened and finally spun into a disc before being cut into panes. The sheets were thicker towards the edge of the disc and were usually installed with the heavier side at the bottom. Other techniques of forming glass panes have been used but it is only the relatively recent float glass processes which have produced good quality flat sheets of glass.

According to his profile he's only 14 so what do you expect?
This website is a safe haven for trolls and haters. I'm done with this pathetic site.
/sigh
How many times do I have to write it... while the original post is not entirely correct, insisting that glass is a solid state matter in the traditional sense is equally stupid. And basing the argument upon thickness of church windows is the biggest stupidity of all. Go study what it means for a matter to be in one of the thermodynamic states and what it takes for matter to switch from one to another. Glass breaks several principles of phase transition in the first order. Since the transition from liquid state of glass to its solid state is basically not happening if described by clasical thermodynamic state transition theory, glass can still be considered in its liquid state even when solid.

how can anything be factually un-natural of this earth? if it all comes from this earth somehow/way/form it is thus, natural...and biproducts must be natural too given the source.

Pitch is the most viscous liquid known to man.

Well, water takes more space when solid then a liquid. Today's truth could always be proven wrong tomorrow.
The fact you are unable to prove that glass is liquid, doesn't mean you are wrong. A scientific mind has to go on hypothesis, and then from 1 to the next, and so on.
The current hypothesis, which seems more likely to be right, is that glass is a solid as other describe it better than me.
