Gee, I hope I don't turn you off.
No way! If everyone were identical, imagine how boring life would be. I just need humor more than most.
One of my biggest thrills in the past year was finally meeting Elayne Boosler at a fundraiser for her animal rescue organization. Her intelligent comedy has been making me laugh for years. http://www.tailsofjoy.net/
Phuck no it can't, as an Atheist or any other part of the universe.
But as a non believer can your life have meaning and purpose without god?
Hmm, not in the absolute divine command sense, but yes. As a matter of fact, I would say I did not find any REAL meaning or value in life UNTIL I accepted that there was NO god. It frees one, and allows them to find actual purpose. Theists have no valuable meaning, because it is a cookie cutter kind of thing. While we are free to shape our lives however we see fit.
