You're right that you cannot say there is definitely no God. There is always that possiblity.

But there is no reason whatsoever to believe that there is that white bearded man in the clouds. There are no facts in God's favor. You only have an old ass book that has been rewritten many times by many different people over a long period of time.

Evolution has been proven, and it is fact. To think some dude in the sky threw together some dirt and created man is insane.

Anyway, when you die, you die. That's it. So make the most of life whilst you can.
