Remember the former intelligence officer that testified before congress that 1st world nations are in a race to reverse engineer alien materials, some of which had actual non humans occupants inside them?
That's David Grusch.
Shortly after that "crazy" testimony everyone though was bullshit, he was appointed as a special advisor to the US government's UAP task force.
I don't think people realize how deep this goes. The CIA officer that said the secrets to this matter are based around the fact that our origins are "indigestible" mentally.
But there's enough actual hoaxes and misidentification out there that you can cling on to that and feel "safe" that none of this is real. The problem is 99.9% of it can be fake and that doesn't mean this isn't real. Only 1 case needs to be real out of thousands.
Logically, it makes no sense that different cultures and eras have been telling similar lies going back to Alexander the Great and the Romans.
