God can't exist because of Eric the God-Eating Magic Penguin. Since Eric is god-eating, by definition he has no choice but to eat God. So, if God exists, he automatically ceases to exist as a result of being eaten.
So, unless you can prove that Eric doesn't exist, God doesn't exist. On the other hand, if you can prove that Eric doesn't exist, then apply that same evidence to God.
There are only two possibilities. Either you can prove that Eric doesn't exist, or you can't. In both cases, it logically follows that God doesn't exist.
Have fun with that one, theists.
Which works well for those with a childish mind, which is probably about 95% of this board.
I prefer to use the one that "If God must exist because the universe is so complex, then God must be so complex he must have been created by a creator, which in turn is in turn so complex it must have been created by a creator. No creator can have just appeared out of nowhere, which then leaves you asking how the first creator was created in order to end up with a God that could create stuff because it couldn't just come out of nowhere."
GOD is the ultimate. There is no time or space without GOD. Let's say one moment before GOD created anything GOD simply was without anything else. Now some might imagine GOD sat around for billions of years and cried. But I find it very logical that GOD was and then there was time, space and matter. and before that was like a blink of an eye for GOD. We do know GOD is love and GOD is capable of love. And GOD intended to interact with HIS CREATION personally and on the "human" level.
Nothing you have said actually counters what I have said.
Your argument has to assume God exists in order for it to be valid in the first place.
If you're saying that God is time, space and matter, then you're saying matter just came into being out of nothing, because God came into being out of nothing.
Therefore the argument that God must exist because nothing can come into being out of nothing, gets thrown out of the window.
