About the Government involvement
I don't have to go over the disinformation mandates given to politicized government employees in the past, to lead taxpayers from the truth for their own good. Maybe you forgive them and feel it Was better for you that you were lied to, maybe not so much. You can easily find these disinformation campaigns even if you agree with the logic.
I am not sure of the logic of the relics coverup. Surely it started out with the military aspect, maybe a secret mission to find out what we are dealing with. "They" have had forty years to deal with the knowledge that we are not alone and have probably come to the same conclusion I have as I finally look at the evidence objectively.
