Sorry, accidentally clicked Post too soon.
One thing we do know is that our sun is a relatively common type.
Given the recently proven abundance of exoplanets in the universe, there is no particular reason to assume that our solar system and its planets are particularly unusual either.
The earth may be extremely unusual. In fact it may be unique. But recently discovered evidence tilts against that assumption, not in its favor.
As I said, I’m interested in reviewing the claims your mention.
Granted, but most of the attributes of our Sun are destructive of life rather than conductive to it. For example, unless the heat of the sun is within a very narrow temperature range life cannot exist. Same with radiation and gamma rays and other emissions. The studies I mentioned are discussed extensively in Norman Geisler's book, "I don't have enough Faith to be an Atheist".
