Life is not unnatural. Humans clearly do not defy the laws of nature, because they can't.
Given the choice between life existing or not on this planet, then the non existing would simply take more effort than the existing (of life.)
Given who's choice?Quote:

We know that the laws of the universe determine that this planet has to harbour life if it takes the path of least energy. Taking the path of least energy is also an observable law of the universe.Quote:

How do you think we know the moon has always been a seperate body to the earth if we didn't observe it when it formed?Quote:

I don't believe this is true. We only know that this planet 'had' to have life in retrospect. We infer from observation that the universe takes the path of least energy, and this is why we believe we know how the Moon was formed.Quote:

There are theories of other universes. Some of these theories are pretty elaborate and will probably be confirmed by the LHC near Geneva. One such theory is called the multi-verse, were our universe is one of an infinite number of universes.Quote:

I respect your decision not to believe/believe, but doesn't seem to change reality?
I really don't think we can know that it would have been impossible for life to have never evolved in this universe - that is something we believe we know with the benefit of hindsight.
What about Boltzmann brains?
That just makes everything all the more difficult.Quote:

The majority of the suspected differences between the universes in the multi-verse are general laws of molecular structure and interaction. Simply put, had several values of molecular integrity in our universe been slightly different, several vital life processes and/or necessities (like water) would have been impossible in the first place.Quote:
