The reason things evolve is so that they can adapt. Life is very persistent. Life can be found pretty much anywhere on our little planet. I have heard the quote "if life can happen, it WILL happen". My question is "why". What purpose does it serve? If we look at life from strictly a scientific standpoint, then we are nothing but chemicals and physics. Why would the chemicals form in such a way that you could consider it life? For what reason does life then keep going? Why does it even matter?
Lots of people have a problem with the possibility that life has no purpose. They don’t have a problem that rocks might have no purpose. Are rocks and life the products of the same thing? Who knows? Opinions vary.
