I went from a fundamentalist community to full blown antitheist to agnostic (after studying religious philosophy in college) to pagan.
My experience teaches me there are many, many great arguments for the existence of the gods. You just have to accept that gods do not fit the conception the christian fundamentalists have: there is no sentient entity in existence that is omniscient, omnipotent, omnipresent and omnibenevolent (towards humanity).
If, and when, you are willing to relax your criteria for what constitutes a god (mine are personifications of the forces of nature) and what your relationship with such a being should look like (I respect them, but worship no one), you too will realize that the “either god is perfect in every way and should be worshipped without a shred of skepticism or there is no god and everything is doomed” mindset is just another arifact of christian zealotry and brainwashing.
