What to do...

[Rev. Rye]

All right, first off: I'm not a born debater, so I need a little help. The kids at my Catholic school have leaned I'm an atheist, and are saying stuff like "Then how was the universe created? How did we get here? Prove god doesn't exist," and all this crap. How can I respond to this? (It doesn't need to be nice)

How was the Universe Created?
Hmm. I don't know that. That's certainly a valid query and one that many scientists are trying to figure out. But really, is the argument that "we don't know how the universe created so therefore God did it," any more valid than the argument that "we don't know much about the origin of the moon, so therefore it's made of cheese?"

How did we get here?
To quote Robin Ince, "The universe existed for 16 billion years, the earth formed 4.6 billion years ago, and it was initially barren of life for the first .6 billion years, but suddenly, amino acid forms, and eventually they flooded the oceans, and they grew and they grew and expanded and expanded, and eventually they formed into unicellular organisms, and the unicellular organisms best adapted to survive thrived and eventually yielded multicellular organisms, and the multicellular organisms best adapted to survive with the atmospheric and changing weather conditions grew and they grew and THUS WE END UP HERE!"

Prove God Doesn't Exist.
One simply cannot prove a negative. One cannot prove definitively that faeries, ogres, and unicorns do not exist, but we seem content to live as if they do not exist. However, since the existence of a God who creates something from nothing violates the basic law of Conservation of Mass, the burden of proof, is in fact, upon you.
