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

[Doubting Thomas]

Atheists, why do you reject the idea of God, and why should I? I know that your answers will include "there's no evidence" and all that, but please try to explain.

I reject the idea of God because, just like Santa Claus, elves, fairies, unicorns, leprechauns, etc, I see no evidence that they actually exist and plenty of evidence to suggest they are just folklore.  The bible is not a perfect book, and there are plenty of glaring errors and contradictions in it.  If you can't accept part of it as true, why accept any of it?

But frankly, I'm not going to tell anyone why they should reject a god they believe in.  If it works for you and you're not a dick about it to those who don't share your faith, then go for it.  I don't have a problem with it as long as the faithful keep it to themselves and out of our secular government.

It sounds like you're having doubts, and that's where I unintentionally started upon my path toward atheism.  I keep looking for answers, and the evidence led me away from omnipotent deities.
