What is wrong with these thoughts?
1) How is it possible to traverse an infinite chain of events? If we experience the present, then an infinite chain of event in reverse is impossible. Basically Zero (the present) - infinity disproves the possibility of time (in a physical reality)...
2) If there was actually a beginning to the known physical universe, then something without a beginning had to have tapped the first domino.
3) Wouldn't this domino tapper, for all practical purposes...be God?
