There is no substance on earth as vital for life as water is.....can it be just a fluke of nature?...or is it evidence of purposeful design?
Yes, it can be a fluke of nature. Why not? There may be gods, but at this point, we have no evidence that can't be accounted for naturalistically, and therefore we have no need for a god hypothesis.
I remember learning about water's unique properties about 30 years ago. Never once did it occur to me that that was a sign of a god's input. I believe that one must already believe in such a god upon reading (or in this case watching) about water to see it as supporting or confirming one's god belief.
The universe is not subject to evolution,
Actually, it is, and it's evolving right now. The Big Bang theory is all about the evolution of the early universe up to the point of vast clouds of neutral hydrogen and helium, followed by the evolution of galaxies and solar systems, then to the advent of life and mind.
The earth is evolving every day. It's coastlines and river courses vary over time. Mountains are thrown up and sea floors become dry land as erosion whittles away at those mountains and returns some of the minerals to the modern sea floors. Continents are moving, colliding, and tearing apart. Earth is warming and sea level changing.The days are lengthening and the moon receding. The sun is consuming its fixed supply of hydrogen.
It's always a mistake for the scientifically unsophisticated to bring scientific arguments to those who have studied it extensively. It's counterproductive, assuming that the purpose is to sway that audience. What is revealed is that the arguer doesn't know the science, which undermine his or her argument, which is usually from incredulity - "I don't see how it could have arisen without an intelligent designer, therefore it didn't."
And all of those things that make life possible did not just come together by accident.
That's an unsupported claim grounded in a desire that that be the case. Although there may be an intelligent designer, there is no reason to believe that there is, and our science has no need of one. Inserting gods into our existing scientific theories gives them no more explanatory power and allows for no additional predictions or practical applications.
Here is all the evidence I need.....you can have your flukes....

The rational skeptic needs more and better evidence than that before accepting any god claim.
Incidentally, I don't believe that the anthropic principle is adequately defined by, "it is unremarkable that this universe has fundamental constants that happen to fall within the narrow range thought to be compatible with life." I believe that its essential message is that it is unremarkable that a creature that can contemplate its existence will find itself in a universe that has the qualities to produce and support that activity. In fact, it's probably required.
