As said previously, it is a military testing site.. I'm just not one to think of aliens.

To be honest with you they could have anything in there. I personally dont reckon that they have extra torrential life there.

area 51 is a underground training camp for ISIS.

I think V5 is hidden there, never to be released.

From what I heard, that's where they are hiding the dankest of memes..

So dank that we can't handle them yet.

Always an interest of mine, I would assume nuclear weapons, test weapons, and the closest sign of extra terrestrial life.

I came up with this theory myself so here me out , I think Area 51 could simply be hiding ... ZILCH meaning nothing . It could simply be just a place to focus everyone's attention to be nothing there. To hide the fact there could be another top secret air base where no one is putting there attention , think about it. The amount of people that know about Area 51 . It could just be a attention grabber. Just my opinion don't get mad if your reading this and thinking what an idiot

They're hiding what they're building, from enemies. Cause let's think of it like this, if you were building something that could potentially insure safety and potentially protect many lives, as well as combat any situation that comes towards us, would you share it with the world during the stage of construction? Or would you keep it a secret so anyone looking to sabotage (AKA: Terrorists) something similar to your project, couldn't cause they don't know you're building it.

Or let's put it like this, let's say an apposing country decides to attack us. Whatever Area 51 kept a secret could possibly be due to the purpose of the enemy not knowing what we have in store for them. We are drastically performing in next gen tech and weaponry, I have no doubt in my mind they have weapons stored waiting to be released if something catastrophic happens.

If we shared what we built the enemies could learn to counter what we would have in store for them. That's what I think they're planning and doing. But of course that's the obvious presumption. They might be doing something completely different. Who knows...

I think it's where 2pac has been hiding for all these years.

Probably technology we will never see for 20-35 years or maybe sooner
