The much more important question is and always has been: WHY are we here? Why do we exist in the first place? For what reason? Who created life forms? Why?
And an even greater question is why is OUR life span so incredibly short as contrasted with the life span of the 'known' universe??? 70 years vs Trillions? What's that about??
Even if we did or were contacted by an alien life form it still would not answer the questions above. So we're here, we exist and we die. Swell. So my ethereal soul is supposed to linger in a heavenly state for trillions of years,...and then what? The whole thing is just too weird.
Hey, I’m not saying this is THE answer, it’s just what works for me...maybe it’ll help, ymmv...
Speaking of Jesus, John said;
All things were made by him; and without him was not any thing made that was made. Jhn 1:3
He was in the world, and the world was made by him Jhn 1:10
Paul said Jesus made Worlds;
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 Hbr 1:2
Through faith we understand that the WORLDS were framed by the word of God Hbr 11:3
Isaiah states the reason Jesus made the world;
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. Isa 45:18
My conclusion?
The WORLDS were not created in vain either, they are inhabited.
We have been told the manner of His return. I believe any perceived or “seeming” contact can be/ might be caused by the enemy to distract. The enemy does have the power;
And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men Rev 13:13
And deceiveth them that dwell on the earth by [the means of] those miracles which he had power to do in the sight of the beast Rev 13:14
