Bible scripture is very clear that the universe is inhabited by a vast number of beings far more advanced than humans and that on occasion, some of these beings interact with humans.
These other beings are comprised of a substance very different from humans, a substance that might be described as nearly incomprehensible to present humans.
Biblical scripture also indicates a uniqueness to earth.
Isa 45:18 "For this is what the LORD says— he who created the heavens, he is God; he who fashioned and made the earth, he founded it; he did not create it to be empty, but formed it to be inhabited— he says: “I am the LORD, and there is no other.
The universe is full of humanoids of various descriptions, few of which are supernatural.
