Whether or not you're a Christian. I believe that it's possible that God could have created life elsewhere because even though it doesn't say that in the Bible,.. it also doesn't say that He didn't.
If there is, I don't think any of them learned how to ever leave or escape the confines of their own solar systems, before they were either destroyed, or destroyed themselves, and their planets possibly, or reset themselves so many times before ever achieving doing so, etc, or ever before God ever Himself stepped in and intervened and "changed" them and their planets and their worlds and lives forever, etc...
Which would have included changing their desires to ever leave their own planets or solar systems, etc, or ever trying to contact and/or make contact and/or ever interact with us ever, after that, etc, forvever after that, etc...
I don't think they ever learned to go beyond the confines of their own solar systems before this or these kinds of things happening to or with them, or or else not happening to or with them, etc...
I also think life on our level is "very rare" also, but that there is life like us out there "somewhere", etc, but so very far apart that we will or would never have and/or get and/or achieve ever having contact or interactions with each other before some of the prior things I already mentioned either happening or not happening, to them or with them, or with them or to them, etc...
And I think that is "by design", etc, or God's design, etc...
God Bless!
