Argument against atheism

[Perhaps]

I hope you understand the fault of that line of thinking lies in the word "presume."

So you would argue that it objectively exists without the need to be brought into existence via consciousness? My point is that you couldn't even possess that thought without consciousness. It's difficult to think about, and I can understand why people would assert that it still exists even if no one is there to think it does. But that goes against the very definition of existence.
