In what way does the Bible mention everything else in the visible world? I have serious doubts about this unless you're classifying in very general terms.
Yes, in a general way.
But under which heading would rational aliens fit under? Made in the image and likeness of God and all?
You can't classify them with "everything that creepeth and moveth upon the earth" because they wouldn't be on earth.
So even in general terms, the Bible conspicuously leaves out any mention of any other rational creatures like Man.
In fact, the Bible might even deny it. Adam didn't find any other one like himself (rational). And don't tell me he didn't know about the other planets and who dwelt thereon. Adam wasn't a caveman, AND he had infused knowledge. He would have asked God for a spaceship, or asked for leave to go build one (he was capable, I might add).
On the other hand, if Adam focused on finding a creature EXACTLY like himself, not just reason/free will but also biology, then another rational alien wouldn't do.
But on the third hand (speaking of aliens!) who says that aliens would be tentacled monsters with 5 eyes? Hollywood Sci-fi, that's who!
Wouldn't God use the same design somewhere else?
