There is not one shred of evidence that life exists anywhere outside of planet Earth. Everything is fanciful and silly, speculative conjecture. That life exists here at all is a miracle of Creation.
Go out on a clear night and look up. Every point of light you see is LIFE.
During the day, look up and the big bright light you see is LIFE.
Proof: Take it away, no LIFE exists.
It is the Sun, the Stars that are LIFE and LIFE GIVING. I suspect life forms are abundant, but it's 'form' all depends on the 'conditions' on each planet. We may not even be able to recognize some of the 'life' on other planets, even if we walked right over it. There may my places that the life forms are so large we mistake them for mountains, or so small that we wouldn't notice them. They may not even be 'flesh' based.
The blueprint for life is built into the mathematics of the tiniest subatomic particle.
That didn’t happen by accident.
