Once again I am going to step in and say that we are making very big statements about EVERYTHING THAT EXISTS when we personally have observed about... less than .00001% of .000001% of .000001% (I am being generous tonight!(also assuming that it is finite and can have a percent value for it)) of everything in the Universe and then stating that we know that ALL OF THE UNIVERSE is cooling so it can't be infinite.

I don't disagree with logic of your statement, but I do disagree with the sentiment behind your statement. Certainly, all of our theories on the subject of cosmology (and much else besides) should always come attached with the caveat "so far as we can tell". But just because we cannot know for certain is no excuse for saying that we can never know and that we shouldn't speculate, build theories and try our best to extend our knowledge, imperfect as our methods are.
