In the observable universe, it is estimated that there are approx. 200 billion galaxies with the Milky Way containing approx. 50.
Based on those numbers, I would not discount the possibility that there is life somewhere out there that is hundreds, if not thousands, of years more advanced in technology than us. Just look how far we have come in the past 100 years. God only knows what awaits us in the next 100 - 200 years.
I wish I could live to see it.....
Why stop with thousands of years? Life from elsewhere could be millions of years ahead of us in technology and intellectual development. That would explain why they stay the heck away from Earth.
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.
Also: Ephesians 3:10
His intent was that now, through the church, the manifold wisdom of God should be made known to the rulers and authorities in the heavenly realms, Ephesians 6:12:
"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
Job 38:7
When the morning stars sang together, and all the sons of God shouted for joy?
