Is it logical to believe that a proof of God's existence or some other sort of "intelligent protector" is the fact that our society exists, in spite of the ever increasing possibility that it very well should have been destroyed due to galactic tragedies such as supernovas exploding near us or gamma rays? Over the billions of years in which we have been evolving, probability says that we should have been destroyed many times.
I agree that it can be unsettling to learn about the profound vulnerability of life. I don't think, however, that life's existence on earth constitutes evidence for God's existence: the universe is large, and for all we know life has failed to begin or has been extinguished many times at many places and we exist at one of those rare spots where life has managed to hang on (so far). Since there is a plausible atheistic explanation of the facts you describe, those mere facts by themselves do not prove that God exists.
