When man can replicate the universe from scratch (meaning from NOTHING) and replicate what we have here now. Then I may be so inclined to worry. But even then, we would be stuck with the question "who made the man who did this."
That's for starters.
Atari cannot load or compute Windows XP; our Atari brains cannot compute God's operating system; we cannot compute "something from nothing" - ponder it, and your brain will smoke like an Atari trying to run Windows XP.
But it's fun to do and that's why this forum exists...
Edited by TheDarin, : The former line "that's why we are here" seemed to imply the purpose for life, rather than the way I restated it.
