1. If god knows the future, why would it create a being doomed to pain, failure, etc. That, IMO, is cruel

2. If god is all-powerful, it either doesn't give a rat's ass about humankind or ignores us altogether.

3. As someone who believes in something bigger than ourselves, I can understand the idea of a convesation with such a being or beings engaged. Worship is another ballpark altogether, and I find it confounding.
