Question

What gives life meaning to an atheist? and what difference, if any, is there between us and animals?
if you say there is no deity, then the only option for how the world came into being is the Big Bang, or a similar random event, followed by evolution, another random event. i am ignoring the possibility that we havent discovered something yet logic can only work with what we know. this effectively means that a logical atheist believes we are the product of a series of unplanned, random flukes. if the flukes were planned, a who did the planning if not a deity, and b they wouldnt be flukes duh!.

Answer

...for the atheists is to believe in their convictions...brbr...the difference being man lives to control man and animals...
