A man named Joe Macias who heads a group of “independent UFO research members based in Illinois” detailed what needs to be done to prevent almost two million people turning up to the top secret military base in Nevada.
Mr Macias said in an email to Express.co.uk: “We are dedicated to this event that has gained international attention, and we are determined by any means necessary to meet these demands.
“The principles of freedom which founded this country shall inform the American public of previously unknown truths.”
Mr Macias has given three demands, which state the “government and Area 51 military base acknowledge the existence of UFO spacecrafts and extraterrestrial aliens”.
The second demand is “that secret classified information about extraterrestrial aliens become available to the public to officially uncover alien conspiracies shrouded in mystery.”
Finally: “We demand that the government and Area 51 military base improve relations and establish an inhabitable co-existence with the public, extraterrestrial aliens, and the US government.”
Although the Facebook event is meant to be humorous, US military is not taking any chances in protecting the top secret base.
A car chase quickly ensued for eight miles, when the suspect exited his car and approached Nevada National Security Site (NNSS) officers with a “cylindrical object” in hand, according to an NNSS statement.
The man failed to adhere to officers’ requests to stop, and was promptly shot dead at the scene.
However, organisers of the page have insisted the event is a joke, and have no plans on storming Area 51.
Facebook user Jackson Barnes wrote in the discussion page: “Hello US government, this is a joke, and I do not actually intend to go ahead with this plan.
“I just thought it would be funny and get me some thumbsy uppies on the Internet. I’m not responsible if people decide to actually storm area 51.”
Area 51 has been used by American aviation authorities since 1955 and is closed off to those without top-level security clearance.
However, the US government did not even admit the base existed until 2013, in a series of documents released as part of a Freedom of Information request, and it is heavily protected by armed guards.
