If the government found intelligent alien life should it keep it a secret?

[HiddenKnowledge]

I think they are obligated to tell us, but I wouldn't blame them for hiding it, when it is to prevent harm to humanity.
If they can prove the 'aliens' are friendly, they should announce it to the world.
If they can prove the 'aliens' are enemy's, they should too.
So, yes, I agree that it should be kept a secret untill they can confirm one of those two.

If the aliens are most likely already dead or unlikely to reach our planet any time soon and they cannot confirm whether they are friendly or not, I think the goverment should be the one to decide whether to tell the people or not. But when in doubt, I would tell them (slowly), since lying won't help anyone in the end.

Obviously, this is just my opinion.
