Aristotle rejected the infinite regress. I wonder why.
Sirlinksalot puts it well: If God is understood as Eternal, everlasting, Omniscient, Omnipotent, Perfect, one who always was and always will be, then this is like asking the question, Who created the one who is Eternal, Everlasting, Omniscient, Omnipotent, Perfect, one who always was and always will be.
The Greeks had it right, something must be eternal. This explains the logical absurdity of atheism. There are only nominal atheists.
LoL.. Now thats funny...
I had this conversation earlier tonight...to definitively rule out the existence of God, one must, quite literally, know everything...if one knows everything, one is omniscient, and by knowing all things, one therefore knows how to accomplish all things, and is therefore omnipotent as well...in other words, one must be divine to rule out the existence of God with any certainty. One without divine qualities can only at best, guess at the matter, making their conclusions every bit a matter of faith as one who believes...
...although faith in the existence of an almighty is indeed, far more logically supportable than faith in the absence thereof.
Bingo!
