My aim here is not to present evidences for God. I'm interested to know if any alternate explanations exist. You're all a bit defensive, so far. Except Hal.
Your use of the word "alternate" here presupposes that "God did it" is, itself, an explanation. But it isn't. What it means is, "An unknowable being did something using unknowable methods for unknowable reasons". Such an "explanation" is no explanation at all.
Relax. We're friends....right? (mostly..)
Pretty much. :-)
