I believe in a greater being than us (god) for several reasons.. which I really don't feel like getting blasted by Mj since he makes very good arguments, but what I find very interesting is:

1. How perfect the earth is, how it recycles everything, etc.
2. How perfect an organism is.
3. How complicated even the human eye is
4. How complicated the Human brain is

To me, I just don't see how we could of evolved into that amount of complicated phenomena...
