@josetogan Who told you there is a conflict between science and God ? many scientist believe in God ! Stop believing in superstitions and rule your mind is my tip.

@moataz Siraj, more than this guy's questioning God, I'm questioning his sanity and maturity. Must be having the time of his life to be able to come out of a hole for this discussion as the reason of his sad and pathetic existence is to try and push his believes on people (on random videos). On the plus side, the video is spot on and hopefully he has learnt a thing or two here. Regarding his theory, he will live to figure out what he calls "superstitions" when the time comes. I've seen many turn around :)

Thanks for the feedback much appreciated. Maybe you should send your professor a link to this video and the playlist on regression :). Make sure you tell your fellow students and like us on facebook (see link in the description of the video). Good luck in your class and let me know if you need/want other videos. I am always looking for ideas. David
