DAVID: Cosmology: milky way size is enormous (Introduction)

DAVID: Our galaxy seems very special, but the current scientific opinion among cosmologists is that our universe is at its basis fine-tuned for life to appear somewhere.

dhw: If all galaxies among an infinity of galaxies are different, a cosmologist could argue that eventually one of them is sure to come up with the right tuning for life. Perhaps that is why so many scientists do not see any need for a designer.

DAVID: You have circled our discussion back to the anthropic principle.

dhw: A vague reference to the “anthropic principle” does not provide any enlightenment at all, I’m afraid. You claimed that the entire universe is fine tuned for life. I claim that the only galaxy we know of that is fine tuned for life is our own. That is why I keep asking why you think your God would have specially designed all the galaxies extant and extinct that are/were not fine tuned for life.

There are many aspects of the universe that seem to confuse you. I just accept it as it is. Your questioning is like the previous criticisms of the backward upside down human retina. We have found the reasons that explain it. I have no idea why the universe is expanding like it is. Does that have a purpose? And then you might ask, if God made life, why will the Earth be destroyed in five billion years when the sun explodes? Perhaps another galaxy will have life by then. Applying human reasoning to God's reasoning doesn't work, but that is your constant attempt in your agnosticism.
