You theists say that there is an omnipotent, omnibenevolent God in charge of the Universe. The implication is that that's a good thing.
You atheists say there isn't.
What if you're both partly right?
What if there is no omnibenevolent God in charge of the universe...
...but there should be?
If that were the truth, neither one of your viewpoints would take us in the right direction.
