If you had access to a comet, or samples, what sorts of things would you look for to see if it’s the sort of environmnet where life could exist?

I was surprised several years ago when they started finding bacteria in deep rock core samples.

What a wonderful universe God gave us!

[John Leland 1789]

Bacteria in deep rock core samples.

What was the species of bacteria? Was it known or unknown prior?

Is the conclusion then that non-living substances in the rock combined to produce life?

Has that ever been duplicated in a laboratory?

Has any scientist witnessed non-living substances getting together to bring forth anything living?

[John Leland 1789]

By the way, I am told by an astronomer that the number of comets known is actually decreasing. Is that correct? How many comets are now observable? How many were observable 50 years ago?
