I think the same. What people call "aliens" are spirits coming out from their dimensions. They can be demons, but they can be angels. And if who sees it doesn't knows who is it, he/she names it to "alien" or something.
But there are some hoaxes. So I don't believe "aliens" living in another galaxy, because the Bible don't speak about it, and GOD in 6000 years didn't told to her children, that there are other creatures...just for non-believers? I can't believe this. But, if there are other creatures, and they can travel with the speed of light, why they handle with us? And Jesus dead for themselves also? Or they can't sinning? Brrrrrrrrrrr........this side of the "aliens" are not true.
So they are spirits, early creatures of the creaton, and in the Bible we can read about their showings. Before Jesus's born there was a big "moving" of spirits(Matthew 1:20-23, Luke 1:26-38, Luke 2:8-16). In Luke 2, when the pastors saw angels, they were afraid, maybe they didn't know who they are....
