The human mind evolved to.search for meaning. Religion isn't about gods.... it is about interpreting the world around us to find meaning.
Atheists do this the same as theists. Most human beings believe things without evidence that they never question. Whether we believe in one or more gods is irrelevant to our need to have beliefs to explain our place in the Universe.

I guess I should clarify that when I said “if there is none”, I was talking about 'meaning' not 'evolution' (in any of its uses).
