All creation groans because of the Curse. God would not have cursed the entire universe for the sins of man if there were other sentient beings out there not guilty of our sin. For those of us who found our thinking in Scripture, the logic is very clear that apart from angelic beings there is no other intelligent life in the universe. Regardless of the “neato factor” that leads most people to blandly assume there must be something out there. (There is, but since it’s not what they want or imagine they ignore it.)
I question the remark ‘there is no other intelligent life in the universe’. All created animals have intelligence of/to some extent and creative purpose. Even trees seem to have intelligence as to when and where to grow. I can buy the statement as/if taken to mean human intelligence.
