I would say no, if there was aliens on Earth they would probably have them somewhere hidden - As Area51 isn't exactly under the radar when everyone knows about it.

If there was to be aliens, they would have to keep it secret because all hell would break loose if it got into the public - What happens when people think they saw a UFO it's all over the news, people panic... Imagine if people fully knew one was here, wouldn't go down to well.

It's an interesting subject but I think Area51 is just a name and it's nothing special.

Area 51 doesn't exsist but groom lake does (AKA area 51) exsist.But im in AFJROTC and my teacher was a luitneat coneal sorry about spelling not the greast and I asked him and he said its an airforce base that does sercert test on PLANES.I belive him so belive what you want

i feel they have something in there that is highly top secret they will never release for public eyes to see probably time travel or a teliport why do i think this?
why is it so top secret that you will be shot dead on sight if caught there.

Im Pretty Sure they have something in there Because if the didnt you wouldnt get shot if you came within 500 yards of the damn place.

I think that they're is something there. I don't know do much about aliens, but it just seems like they're way too secretive. I know it's a base and they need to be, but violators will be shot and so on? There is obviously something we don't need to see
