Everything that has been ascribed to god, when investigated, has turned out to have natural explanations.
But that is by the by, I think the biggest thing against gods are that they are a stupid and rather childish way of looking at things.
If you say to a toddler that fish live in the sea they will they will assume that the sea is there to give the fish a home. Most people grow out of this view as they grow up but it is comparable to the theistic world view. "The world is here to give us a place to live", "so someone must have made it for us" the minds of toddlers in adult bodies.

You can fix ignorance, you can't fix stupid.
