No, we do not know for sure that the universe is finite. Furthermore, the non-existence of God is not an assumption or biased in any way; it's merely evident at this point because there is no evidence to support the claim that God's exists. For this reason (the lack of evidence to substantiate the claim) proposing the existence of God must be factual, is the assuming and biased position. Lastly, in regards to this: [i][b]Your assuming whether it is or isn't infinite to back up what?[/i][/b] - SSG ACM I'm not trying to back up a proposition in either case; that's exactly what you are trying to do, it seems, since the premise of your argument is the following: [i][b]Would it not make sense for an infinite cause to be necessary for the possibility of existence for finite things? Then what would you assume to be the infinite cause if not God?[/i][/b] - SSG ACM Which is bizarre, because now you're saying the universe is finite, when before you were basically assuming the universe is infinite, and that this some how equates to the existence of God. And I'm saying, no; we do not know if the universe is infinite, and in either case, that doesn't mean you've proved the existence of God at all.
