I don't care enough about aliens to have an opinion. I haven't seen one, and the "abundance of testimony" convinces me of alien existence no more than religious gospel.

> the "government authroity" of a "respect country" stating unequivocally that the reality of "alien" contact is true

Stating the existence of aliens is not unequivocal or based in reality, even if a government does it. Don't forget that Russia claimed to cure cancer a few years ago, we've yet to see how unequivocally true that is in reality.
