This is not necessarily true. There have been physicists who claiml they have been able to identify at least 25 finely tuned variables (ie, temperature, gravitational force, radiation level, etc. etc.) which must all be present for life as we know it to exist. The probabiliity against all or even half of these finely tuned variables to be present on any given planet is off the charts. Something like 10 to the negative 250th power or, in other words, impossible.
Would be interested in reviewing these claims.
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.
Ah, the old “not necessarily true” gambit.
Actually, it’s not at all true.
The more we find out about our place here and the conditions necessary for life,
the more it looks like the Earth is unique.
Even given the number of stars that we conjecture exist, the odds are still greater against even ONE earth existing.
