I always find these sorts of religious discussions ridiculous. Believe in god if it gives you comfort, but as far as I am concerned god does not exist. Just because you believe in god does not make you a more righteous/better person - in fact some of the worst atrocities/deeds have been done by religious people following their interpretation of their cause. Reality is you can get allot of comfort from believing in an after-life and nothingness can be plain scary but IMHO is the reality.
Just one question for those that believe in god - who created god? He/she/it had to come from somewhere after-all.
