No. The Bible tells us that God created humans and angels, and there were fallen angels (demons). There's no mention of aliens or life on other planets or even other planets as far as that is concerned. Earth is the focus of God’s creation and redemption plan.

There’s no mention of lots of things in the Bible which clearly exist. It is not an encyclopedia.
I’m not saying aliens exist, I’m just saying that’s not proof they do not.
Jesus died in one specific place, but the effect is not just for that place, or even just for Earth. All of Creation is groaning, and all of Creation will be made new.
If aliens do exist, I don’t see how it’s any different than still-unreached human cultures existing.
the problem is that the distances are so vast, the chances of humans developing the tech to travel to those places is nearly impossible.
there is also the issue of our cellular clocks. they are connected on a protein level to the earth's 24 hour rotation.
We can't take the gospel to other planets. They will have to come here for it.
Are they fallen race ? And the angels and demon idea does not make too much sence bc angles and demons are sperits and would not need any spacecraft to get around :)
