Aliens exist but also dont exist.

Well according to Ancient Aliens in History channel, aliens have been visiting Earth for quite a while. I've seen documentaries about UFO sightings, abduction, and I too believe they exist for the universe is so huge there must be someone else besides us. We're here, so why can't they be where they are?

I am also have lot of confusion regarding it.. Also read lot of articles too.. But not understanding it is true or false...

They can go here if they have the means. But I don't think they would even want to meet us.

I'm not aware of that.

I guess it depends what you mean by an alien... do you mean a being/animal, bacteria or plant?

Universe means unknown and in believable incidents together.. Not possible to understand by human beings...

So does Superman exist? He's an alien.

I also think there must be some life out there, even if it's just alien plant life. the universe is far too big for us to be the only ones out here.

I have heard a lot aliens that they do exist but there's no enough evidence for that.

We will never know what exactly is out there in the universe. Perhaps we are not meant to know.

We earthlings are not alone in this universe. There may be life and human fòrms in far away galaxies. Hard to believe that Earth is the only planet or celestial body that sustains life.

Honestly, I think it's possible that there are other life forms outside earth. Also, Pentagon officially released a footage a UFO sighting. What do you think?
