Well, it sounds like you gave it your best shot!
I would have said that I can't prove it. I doubt anyone can. But the whole point of Bible is following God and having faith and trust in him, even when you seem to be alone. There was this quote in "Polar Express," and although it is about Santa, I think it works for God, too! It was "Seeing isn't believing, but believing is seeing."
Also, why would I want to go through life without God and Jesus? They give purpose to our lives, help us lead good ones. Hey, there's even the possibility that there is no God- but I don't and won't ever take that chance that there isn't.
It's cool you guys are both Christians- so are my crush and I! Well, we go to a Christian school, so.... lol
