'Why does God allow suffering?'

That was a very honest post.  I wish I had a better answer than this: I felt that way, too, many years ago, and I became agnostic because of it.  First, an agnostic theist, then an agnostic atheist.  But that was my personal journey.

Earlier humans had a limited awareness of the world around them, and their religious beliefs were influenced by that.  Now, in this age of burgeoning science, that view of a supreme being is inconsistent with what you term an Omnigod.  Good word, actually.  And, where does free will fit in all of that? 

Given the vastness of the universe, how could there be a god who created everything, yet still interacts with individual humans? And there are countless variations of human religions, with equally countless contradictions of what is right and what is wrong.
