Are We Ready To Know What’s Out There?

Steven Spielberg's Disclosure Day is released today and is being called the third act of the Spielberg Alien trilogy after Close Encounters and ET but this one is about exposing the government's cover-up of extraterrestrial secrets, a well trodden conspiracy theory which began in 1947 when a UFO supposedly crash in Roswell, New Mexico.
After both of the previous films, there was a dramatic increase in reported UFO sightings and we can expect more this time also and in 2021 a US government report was released that showed they had investigated decades of unexplained aerial sightings in US airspace and there were 20 unidentified flying objects that they are unable to explain but did not rule out rule out extraterrestrial activity as a possible explanation.
What i always tell people getting over excited about aliens visiting is that what they are talking about is UFO's with extra emphasis, italics and underlining of the Unidentified part of those three words but Spielberg himself has said that there is now a critical mass of people fascinated with the question of whether we are alone in the Universe, and if someone knows we're not alone, why haven't we been told but i wonder if aliens do exist, should we be told and if we were, how would we react?
In February, former president Barack Obama said aliens were real before hastily clarifying that he hadn’t seen any evidence but then, would he tell us anyway?
In HG Wells’ classic sci-fi novel The War of the Worlds, alien arrival prompts societal collapse as people flee from cities and in Carl Sagan’s novel Contact, the existence of aliens sends religious groups into mass panic and History is littered with examples of new information about our place in the Cosmos not going down well.
Giordano Bruno was burned at the stake for his theory that every star was a sun and had it's own planets, Galileo Galilei was sentenced to permanent house arrest for saying the Earth was not the center of the Universe and Nicolaus Copernicus only avoided a similar fate by releasing his heliocentric model theory by dying very soon after.
My own view is that Aliens MUST exist because there are just far too many planets in the Universe where life could have started but do i believe they are coming here in Spaceships and a Government has covered it all up?   
No i don't as the sheer distances involved would make it unfeasible but i live in hope that one day something other worldy might turn up and asked to be taken to our leader and that would start the argument how who exactly the leader would be because there are a few at the moment who if they met, would lead to them to decide to go ahead with the Hitch Hikers Guide to The Galaxy solution of demolishing the Earth to make way for a hyperspace bypass.
