Quote:No one can say that God exists or doesnt, it all speculation. However, what was the cause for the universe? I also find the ontological argument is rather convincing, that God is the greatest thought or idea that can be imagined.
"The greatest thought that can be imagined": i think that the word you used, "imagine", pretty much sums it up. You can imagine the greatest thing possible, this has no impact or implication in the real world.
I do not know the cause of the Universe, but there can be hundreds of explanation for it, God only being one of them. As such, you are using the "God of the Gaps" argument here: i do not know how it happened, so God did it.
Quote:So your second refutation is, 'I dont understand it, therefore God doesnt exist.'?
Of course not, i'm saying that you may create a logical reasoning for God's existence, but at some point in it there is an unprovable assumption in the reasoning, even if the rest of the reasoning is valid. To have the power to be he must already be, so this argument can explain how God can continue to exist, but now how he came to be, making it useless.
