Sorry Alien but that is ridiculous.
Area 51 has been a development and testing facility for experimental aircraft and weapons systems since the cold war. The extreme secrecy enveloping the place
[because of the cold war] began with the the U2 project and its flight testing and programs that couldn't be conducted at Edwards Air Force Base. All that secrecy simply led to the more imaginative parts of the population to go;
"Oh look "Aliens" are kept there! I haven't seen them but surely they "must be", the governments always lying to us!" Alien, the worlds not one big X-Com game, there are not groups of Men in Black running about wiping peoples minds, really theres not.
Those numpties sitting out in the cold at night looking up & over Groom Lake going
"Oooh look ... pretty lights! Wow! Our aircraft can't do that, must be aliens, or at least alien tech!" Nonsense! If the same people had gone back to the late 50s and seen the
Lockheed SR-71 being developed they would have been doing the whole; "Oooh look ... pretty lights! Spaceship! Wow! Our aircraft can't do that, its too fast ... must be aliens, or at least alien tech!!!" See the pattern?
You don't subscribe to conspiracy theories? You just did.
Thats extremely flawed thinking Alien, do you think the US is the only space agency out there? Do you think the US is the only government on this planet? More still, do you think that "if" aliens turned up on our planetary doorstep they would go, "Ooooh look Americans! lets go talk to them first! Better still lets come light years and crash a few of our craft on their planet and get a few of us captured, yes ... lets do that!" Its ridiculous nonsense built out of cold war fears echoing through the decades.
I think you're forgetting or maybe not in the know that people were still hypothesizing that there were trees, plants and life possibly living on Mars right up until
Mariner 9 got there in 1971. At that point all of the hype of "little green men" died off when Mariner 9 just began photographing Mars regolith. Well, that is until twits like Richard C. Hoagland came along and began pushing the whole Remote Viewing angle with cities and faces on Mars. Guess what? More piffel! That ran and ran until
Mars Global Surveyor obtained images and blew the whole thing out of the water.
No, it's money grabbing nonsense pushed along and fed by ignorant minds. I'd suggest you take a look at some real science and see what humans are actually capable of rather than relying on imaginary aliens to fill in the gaps. Lastly, yes it is probable that there is extraterrestrial life of some sort out there but until we have actual, verifiable proof its moot to make the argument that it exists.
Edit: And whilst we are on the alien thing ... ever thought to wonder why all aliens spoken about are humanoid? Look around the planet Earth here for a moment. With all of the millions of different creatures, all different lines of evolution here, theres going to be a group of aliens out there that just so happened to have evolved from apes on their planet too? Ridiculous nonsense! If dinosaurs hadn't have been wiped out by the K/T impact some 65 million years ago, it would be highly doubtful mammals would have gotten this far, let alone got to the evolution of homosapiens. Yet humanoid looking aliens had a free run at it on their planet? They have a K/T event too? Better still, the galaxy is populated by humanoids and Star Trek is right! Can you see how ridiculous this is getting?
Meh! You have me on a rant now!
