and if mankind is so solid and focused and great in his thinking, why then is the world in a fucking mess?
Thats an easy one. Look at the history of the children of Abraham and you'll find that answer. Remove the Jews, Christians and Muslims from the equation and history much less present day isn't so "messy".
I fall back on Occam's razor (That sounds worse than it is!), I think, what is the simpler explanation, a supreme being creating the universe or the universe just is. Since the universe is here and I can see it I'll go with that and follow the science that seeks to increase our understanding of how and why. Why must there be something outside the universe? Outside time? Why does it disturb you that things may just be?
It certainly doesn't help me when folks of religious bent,exhibit intolerant and immoral behavior on such a regular basis, leaving those of us who are undecided with a bad taste in our mouths. If atheism requires religion to acquire the base of morality it is only by observing what the religions have done and live otherwise.
One other thing that keeps me away from any belief in god is the fact that cultures separated by geography and/or time don't come up with the same theology. If it were so logical why don't there exist Identical or nearly so, theologies? If the european, australian and african aboriginal populations came up with similar visions of the godhead I would give the theory more credence, but they don't, and I am left with the feeling that your guess is no better than any other and no more than wild speculation based in superstition.
P.S. benz rider, you're assertions remind me of this joke;
A Kindergarten student was working diligently on a drawing in class, the teacher checking on her pupils' progress stopped and asked this girl what she was drawing. "I'm drawing god" the little girl replied, the teacher paused and said "But no one knows what god looks like" Continuing to draw and without missing a beat the girl replied "They will in a minute"
