Asking what life means is like asking what is the shape of fear, or what time is yellow. It is not a sensible question. You began your last post by saying "It is not possible to know what preceded the big bang...". I agree with you up to that point. Where science and religion differ is whereas science is open about not knowing the answers but is working towards them, religion claims to already have it all sewn up. On the basis of an old book. Written by humans, thousands of years ago. Science or faith? Now, are you absolutely sure you're atheist?
