It seems to me that God crammed life into every possible space on Earth - we’re even discovering organisms living in environments we wouldn’t have thought possible a hundred years ago. Why would He then be stingy with Life in outer space?
Makes no sense.
Heb 1:2
Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
Heb 11:3
Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
Worlds, plural, more than one. Then:
Isa 45:18
For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the LORD; and there is none else.
I don’t think He created the other worlds in vain either – he formed them to be inhabited as well.
