What has Christianity ever done for humanity?

[useful idiot]

Okay seriously, if Christianity didn't exist, we'd be farther along technologically and not have annoying evangelicals who picket soldiers' funerals (as a guy in the military and Navy sailor, this is infuriating).

Yawn.

I don't accept the premise of the question. What do you mean by Christianity? Are we talking about organized religion, or the truthfulness of the claims found within the Bible?

In one sense I would say that if Christianity did not exist then we wouldn't be having this conversation because the universe would cease to exist. If we're talking about organized religion, then you can't calculate the ways it has shaped and influenced Western civilization, the dominant, and probably most progressive, civilization on earth. Almost every single thing would be different.

As a determinist, I tend to think everything is related to prior events and interconnected in some way. Even if it was made up, then it was inevitable and touches most things in the world in a number of areas.

Westboro Baptist Church is not Evangelical btw. They specifically don't evangelize, they're hyper-Calvinists(which is antithetical to actual Calvinism), and they're so extreme and distorted that most hyper-Calvinists wouldn't even claim them.

And why exactly would the universe not exist if Christianity didn't?

I accept it as true. If God doesn't exist, the God of the Bible, then neither do we. You're absolutely free to disagree, and I know you do.

That makes no sense whatsoever. The fact that we exist is pretty well accepted. If the God of the Bible doesn't exist, we continue to exist and Christianity is merely incorrect.

I should have said "neither would we". The question, if it was intended in that way, would be akin to saying "What has the planet done for humanity?". It wasn't intended that way however, because the OP was clearly operating on the assumption that Christianity was merely a belief system made up of rituals and holy books like any other. I disagree with that but went along with it.
