Presumably there is indeed no purpose in the ultimate fate of the cosmos, but do any of us really tie our life's hopes to the ultimate fate of the cosmos anyway? Of course we don't; not if we are sane. Our lives are ruled by all sorts of closer, warmer, human ambitions and perceptions.
Richard DawkinsThe beauty of evolution is that it does provide an explanation of how you can get complexity out of simplicity. It does it by slow, gradual degree. At no point are you postulating the sudden coming into existence of a complicated being.
