In 20 words or less, prove or disprove the existence of God.

I'd appreciate not turning this into "belittle Christianity in 20 words or less." Come on r/atheism; you're better than that. I personally am an atheist, but as I know most arguments will be for the disproof I'll start off with one for the proof:

Nothing can move without being moved. Something must have been first. That is God.

A side-rant you need not read: Don't approach this as a task of explaining what believe to people in 20 words or less. This is to be able to make an argument one way or another, and I extremely reccomend trying to do so from a belief you don't have. It's a good skill to have. And a note to all the people who hate on Christians and troll them: you might get a good laugh out of it but you're just being an asshole. And whenever someone is being an asshole, you don't try to see things from their point of view. You think "wow, this guy is an asshole. fuck what he thinks." this makes doubting Christians stay Christian, because who wants to hang out with a bunch of assholes.
