Very nice questions
1st question : *I* am not Craig James Willy. I am something (which might as well be called a spirit or soul) that uses Craig's body and life as a window to see the universe.
I am me because I see things through the eyes of Craig and not the eyes of anyone else.. I am not me because of my genes, name or any environmental factors. They define my body, one thing defines ME : I am linked to this body.
Err.. hoped that made some sense
2nd question :The birth of the universe was decided with utter complete 100% randomness. Think about it, something so fundamental as the universe cannot have been created except by randomness. We can always ask : "why was it god who made it? why did we start out with rock that blew up?"
To me, randomness in a sense "decided" what the rules of the universe would be (this randomness might as well be called God I suppose) because Ocam's Razor cannot slice this off. It IS the simplest explanation possible.
I believe the second AFTER these rules were created by randomness, there was the big bang and science explains most of it.
The neat thing about this randomness idea is that it can never be ruled out. Science or religion can decide anything to be the begining of the universe and it still could have been brought about by randomness.
