Why ufos are kept secret?

Answer 1

The Extraterrestrial Beings who come in The UFOs are technologically thousands of years ahead of human beings. The US and its allies are afraid that if they are able to contact people of all nations on earth freely and openly, then all these nations and their people would no longer look to western so-called developed countries for leadership. Instead the people of the world would follow the ETs not only in technology terms, but also politically, economically and cultural and religious terms. The US and its allies would no longer be leaders, capitalism would not be considered the 'best' economic system, 'Christianity' would no longer be the most dominant religion. In other words it would be the end of Western Anglo-Saxon dominance of the world.

The problem for the ETs is that they can not approach the people of the world openly unless they are invited by the major governments - Cosmic Law prohibits them from doing that - that would infringe on the free-will of human beings. So there is catch-22 - the ETs can not show themselves without an invitation and the powerful Western countries (mainly the US) deliberately keep their presence a secret and refuse to let them reveal themselves. The ETs with their advanced spaceships would never breach Cosmic Law and bypass the governments.

Answer 2

AnswerWe don't know half of our government is a secret they have top secret info that the government won't show us. But it's hard to keep a secret so big it's gonna eventually by someone that either worked for Area 51 or some other top secret base that we don't know about will come out and tell us the truth on what's going on.
Final AnswerI believe that the government just feels we don't need to know the truth on what's really going on there's not really a known answer to your question because we don't know why the government decides to hide info like this. But we are entitled to know.
