Islam owns atheism with a single verse

[Loaded dice]

A real god would have to be the totality of Reality, 

That's called pantheism, Bucky, we're not entitled to it. You're just replacing the word reality with God. In other words, you made the word God meaningless, congratulations!

Reality is larger than your god,

I doubt you can define what you mean by larger here. But let's assume you're right, great, so what?

Does reality being "larger" than God disprove his omnipotence ? No, because God can still act in whatever way He wants in any corner of reality.

Does reality being "larger" than God disprove his omniscience ? No, because God can know everything about reality, even though He doesn't "occupy" it at all times.

So... did you think this through?
