Entropy does NO SUCH THING!

Where did you get this idea?

Entropy ALWAYS relates to the entire system ... not just some human defined subset of the system. Arguments to the contrary are promulgated by the nutiest of the theological fringe but have nothing to do with science.

Living systems by definition interact with systems external to themselves. Thus your belief system has no foundation and with it goes the conclusion you have drawn.
