but hey ! if we cannot get through the van allen belt , maybe they can't either ?

radiation shielding and magnets. they get theough fine.

i thought this was pretty interesting then take this in account .

they say that : the radiation in space is extremely high , and only when you have an atmosphere you can have some protection , a spacesuit or spaceship has no atmosphere ... also since space is as good as 99.9% vacume , rocket engines that require air ( atmosphere ) are useless .

Of course they exist. We would be selfish to think otherwise.

There is enough 'evidence' out there to believe they exist. If you are truly interested in EBE's and their technologies (or the man-made ones!), look up Dr. Steven Greer. Better yet, I think his latest movie Unacknowledged is finally out, but check out his previous works too.

On YouTube you have many videos, statements, documentaries, and yes, half of it could be considered hoaxes. Popular channels are SecureTeam10 (credible), Streetcap1 and ThirdPhaseOfMoon (I find him a bit off sometimes,but he has a lot of content).

Also, if you see something in the sky which you can't explain, remember 90% of it is probably man-made with humans in it. Look up Operation High-Jump.

I've looked at some of his stuff, I'm really like the research he's done and think he's on the right path.

Since the universe is infinite seems to be infinite and is continuously expanding, it is very unlikely we are the only planet with life. There are over 100 billion galaxies in our universe. There is a very very good chance that there is other life somewhere out there.

Edit: wording/phrasing/redaction whatever you wanna call it

Edit2: @WaterT , this may answer your question: Dr. Michio Kaku on the existence of aliens.

Another cool video on the existence of aliens by the same doctor.

Since the universe is infinite

Proven otherwise, but hey.

I've been searching now, but I haven't found this proof?

Everything says we don't know for sure, but as far as we know there is nothing outside of the universe and that the universe doesn't seem to have an end.

Edit: After more research, everything points to the universe expanding as well. I found a NASA article released last year stating that the universe is expanding at a faster rate than it was previously thought to have been expanding.

Edit2: It seems like the consensus is that since it's expanding it points to it being infinite, but it can be finite. They are not totally sure.

Here's the sources for that:

@Tallest_Skil can you give me a link or something to go off of, because I can't find this proof?

They are out there. Possibly illegally among us.
