Cosmology: milky way size is enormous (Introduction)

dhw: Rareness is not the same as uniqueness, and even if it is true that life can only occur in big galaxies, we do not have a clue how many big galaxies there are in the universe. In all honesty, I don’t see the point of this article. And one can’t help wondering why your God bothered with all the small galaxies if his only purpose was to produce H. sapiens.

DAVID: You may have forgotten, but one of the requirements of life is a planet which is far from the dangerous activity in the center of a galaxy. The Milky Way grew/grows by swallowing smaller galaxies, and we sit out at the two-thirds point on the second spiral arm in a quiet neighborhood. Same evolutionary story you try to deny as God's method: start a universe, evolve it, grow/evolve the right-sized galaxy, create a perfect Earth planet and evolve it for life to start, evolve life to create humans. All in the history presented.

I have never denied the process of evolution, and if God exists, of course evolution was his method of achieving whatever may have been his purpose. What I object to is the blinkered insistence that the whole of evolution (and let’s not forget that according to you every phase is specially designed) had the sole purpose of producing H. sapiens. So please explain why you think your always-totally-in-control God specially designed all the wrong-sized galaxies if his purpose was to specially design the right-sized galaxy to create humans.
