Please present positive arguments why you think atheism is true

[simplexity]

Your brain.

And how do use your brain to deduce God?

See a materialist has to say "I don't know" a lot. Nothing wrong with that, except there are a lot of useful things he could know if he made a few intelligent links. Things fall together, a good solution works out from an hypothesis. A materialist almost denies the human ability to think. Thinking is dangerous because it moves out of the realm of certainty.

Yes, but there is no reason to move to a place so far outside of certainty that it is just completely made up.

You insist that I make extraordinary claims where I make none.

An absolute, all-powerful God does not count as an extraordinary claim?
