The big bang theory says nothing of the sort, that's just you projecting your own insecurities on it. Life can be meaningful without a god. That's up to you. I, for one, believe my life is meant for something more than becoming an eternal lapdog in heaven.<quoted text>
A big difference. Big bang theory pretty much states that all life is a major mistake and really shouldn't have happened because it's meaningless. So if evolution was driven by survival, then something must drive survival (like purpose) or else nothing would have ever survived because, remember, life is meaningless.(as the person who made the original statement believes it is.
Your evolution/survival/purpose argument makes no sense whatsoever. Evolution does not need to have "meaning" to work. That is absurd.
