D Morgans - if you are satisfied with infinite regression as opposed to a First Cause, then just think, time itself would be infinite,and so today has not yet arrived!
Crazy stuff man!
But if you agree with a beginning, then there has to be a first cause, a creator of physical laws, and something for those laws to act upon.
And consider this. If God created man, with only his five senses, who is to say that God left the detection and interaction with the spirit world, only to those who are prepared to look, and are endowed with the humility to acknowledge a power higher than themselves.
This is at least plausible, and provides the possibility of a meaningful dialogue.
