Why does science always upstage God?

[Mister Agenda]

I already granted that there’s not God to start this conversation so that we could fully explore the inconsistency in the atheist moral worldview.

FFS, there isn't an 'atheist moral worldview'. And if you thought about it for one minute, you'd realize there isn't a 'theist moral worldview either'. If all you know about a person is that they're a theist or an atheist, you don't have enough information yet to infer their moral worldivew.
