But now The Disclosure Activists claim and number of recent UFO file declassifications, means the lid is about to come off once and for all.
In a statement, the organisation said “the historical stance of widespread denial and misinformation has shifted”.
Group, co-founder Russell Calka: “Recently there is a systematic effort from within the US and other world governments to release this information to the public.”
Victor Viggiani, the senior strategic adviser to organisation, added: “All of the evidence that has been accumulated by researchers, military witness testimony, and acquired from declassified government documents over the last 70 years points to three very basic conclusions — the planet Earth has been and is being engaged by off-world civilisations.
The Disclosure Activists claim we are aboutto receive big news about aliens.
The statement added: “The Disclosure Activists contend that Disclosure is already underway.
“Earlier this month, the Spanish Ministry of Defence released a cache of previously classified UFO documents, similar to documents released by the Central Intelligence Agency (CIA) in January 2017, and similar to other document releases from governments in the UK, Chile, and Mexico.
“NASA reported the discovery of additional habitable exoplanets (bringing the total to well over 3000) and just this month, former President George W Bush alluded to his knowledge of the UFO phenomenon in an interview on late night television with Jimmy Kimmel.
