Interesting post. I would add that if CREATION is true, the same conclusion follows.
Accordingly, if either creation or evolution is true, then, most likely, this is it.
(which I think, personally, is very much the case....).
No, if Creation is true the Creator is free to create life on any number of planets in any form of life He chooses, including life more advanced than humans, life that may have built AI collectives. I would say that if human-like life exists on other planets that is additional proof of a Creator. With Evolution though, one would predict that the life on other planets would be extremely variable with the likelyood of the existence of human-like life quite remote.
