Life is finely tuned to the universe. More specifically the laws of nature which govern the behavior of the universe.I see that. I stated as a Chem major and still remember some of this stuff. Took 2 semesters of organic chemistry.
Ding does not realize how strenuously (though clumsily) he is arguing that life is fine tuned to the universe, not the other way around. That's what faith does to a person's brain.
This all goes on the same shelf with Hoyle's fallacy. You touched on this with Zeno's paradox of motion.
They think they are arguing about the existence of life, but they are actually arguing about life "exactly as we find it on earth". We have no good reason to think different life isn't elsewhere in the universe -- or even in other universes with different physical laws -- preforming the same functions with different physical laws and chemistry.
It's like trying to say the Arctic circle is fine tuned to polar bears or white fur.
Uh, no, polar bears are fine tuned to the environment above the arctic circle.
Why would you expect life elsewhere in the universe to be materially different than life here? I wouldn't. The same laws of nature that fined tuned life here would be at work everywhere.
