Have aliens visited earth?
 

Was curious what OOT thought (a group of mostly well educated people)

Re: Have aliens visited earth?
 

id say its probable for other intelligent life to exist somewhere. getting here is highly unlikely.

I think its pretty foolish to think we are the only life forms in the entire universe

I am unsure if any said life form has visited earth tho. I know there are tons of limitations that many argue make it impossible, but I also know we dont know all there is to know, so I definately think it could be possible. Im undecided tho, It wouldnt suprise me if it had happened, but I think pretty much all "crop circles" and "ufo sightings" and "governement coverups" are bogus. I think if aliens did come to earth, theyd have the technology to make it so that we never saw them.

IMO, it would have been better if the first question specified "intelligent" life. It seems really, really unlikely that no form of life whatsoever has ever developed on another planet.

Considering the alien's obsession with SIIHP, I think its possible to assert that they are browsing OOT as we speak.

Wait, there is intelligent life on earth? Whoa.

Re: Have aliens visited earth?
 

some people (intelligent ones!) think all life on Earth was created by simple cell's organisms that arrived on Earth via meteors or other galactic explosions.

does that count?

it is certainly possible to travel insane distances in space. However to do said traveling would require much much more advanced technology and many resources.

If aliens did visit earth, why wouldnt they want to greet us? also if they were here, i wouldnt think the gov't would have the power to stop them or hide them.

Re: Have aliens visited earth?
 

It doesn't seem almost equally unlikely that no form of intelligent life has ever formed on another planet?

Let's define "intelligence" as chimp-smart, just for laughs.

Actually, the conditions for life to exist are extremely rare. Life as we know it is extremely fragile and it appears, based on probabilistic arguments, that the conditions for life to exist are not that common in the universe. Microbes quite likely exist in abundance but complex life not. This argument was first set forth in the book Rare Earth: Why Complex Life is Uncommon in the Universe by Peter Ward, Donald Brownlee.
