I'm over 50 and this documentary finally convinced me that we are being visited by others of some sort. Whether they are from another planet or the future or something else is of course undetermined.
But so many reliable witnesses as well as the captured footage is convincing. If the former Senate majority leader believes then you probably should too.
The two events witnessed by multiple children are also very convincing. There is no way you can get 20 or 30 kids to agree on a lie and flawlessly maintain the lie over decades.
They very likely have stealth technology, so the one comment that stands out is "why are they allowing themselves to be seen at all."
My guess would be to prepare us for an eventual public contact. But hey who knows. Maybe their stealth technology is unreliable :)
