Intelligent lifeforms, i mean.

I will never believe in aliens. Until I see it.

I belive in the live outside Earth.

I don't belive that they ever visited earth.
And I don't belive they own any advanced technology.

Yes, I do believe in aliens. (Or more likely a form of life outside the Earth)
No, I do not believe they did visit Earth at all, nor they've build something on it.

There are billions upon billions of more galaxies, each containing billions upon billions of solar systems, each containing a handful of planets. I see no reason to deny the existence of other beings beyond the solar system. Would they find us? Doubtful.

The possibility of other life forms in the galaxy is actually very high considering how big space is, and how many stars there are, how many planets are on each star, and the possibility of each planet having water and the ability to sustain life.

Wow that was a mouthfull. But you get my point. If they are more advanced then us, or are just simple minded animals, or even micro-organisms; we won't know untill we find them, or they find us.

We don't and will never know how old the universe and galaxies are.
Therefore "aliens" may have a billion times more generations than we do and by that time they would have advanced farther than we can imagine today.
Yes I do believe in Extraterrestrial Life and I do believe in "Aliens"

I just wish we had the chance to advance in such a way without killing ourselves first

Yes, I do believe in 'Aliens' although our countries first reaction would to fire multiple nukes, shoot the body, burn it, and claim it was just a fallen weather balloon. Sigh

I believe there may be some kind of life out there but I dont think they are intelligent. I think that the whole intelligent life form, advanced technology, and visiting earth thing is just from some kind of movie. The fact that no one has actually seen them or met with them just tells you.

There has to be something. Whether it be intelligent beings, or not.
