Atheists, tell me, a Roman Catholic: why should I become an atheist?

[GUBU]

Toranic and biblical depictions of a "maximally great" yhwh shows a being that can do less than what humanity is currently capable of. Hence yhwh isn't a maximally great being.

What would be some specific examples of this?

Lessee, humans can induce speciation; humans can split the atom (allied to this they can turn lead to gold); humans know what's in space; humans know how the world started; humans can calculate pi correctly; humans can get through the Sinai peninsula in less than two weeks on foot (on god's directions Moshe died after not being able to get out of there forty years in); humans have many ways to defeat iron chariots; humans understand the ways diseases propogate and have means to combat many of them; humans understand madness much better than yhwh did (protip; demons don't cause madness).

And that's before I start thinking about and researching the subject.
