But the chance of there being some supernatural power is non-existant. The universe is probably infinite which means even with a 0.0000000000000001% chance (add a few more million zeros between 0 and 1) there is still a good chance that SEVERAL places in the universe has intellegent life. Even though the human race is very advanced in technology, we still can't travel between galaxies, or planets for that matter, so we are not able to find the life we want to find.
But by that token, in the infinitely expanding galaxy, who's to say there aren't things out there beyond comprehension? I don't doubt that there's intelligent life somewhere out there, but in an infinite universe with infinite possibilities, I find it hard to rule out that somewhere out there exists a being (or, beings) that would seem to us like deities- and may even be so.
There's only one way for us to find out though. Helmsman, set course for the Delta Quadrant, warp factor 9.
