here is my theory on this subject, if you had the leaders of every country and every religious group and the top scientests in the world all on one bus with a live television camera crew film ing and a UFO landed in the road and all of those people were filmed talking and interacting with these "aliens" and even if a few of our leaders got on the ship and left with them, probably 1/2 of the population would probaly still not believe in exterrestial life.people dont like to get out of their comfort zones no matter how wrong they are, for gods sake look at those antifa idots out there being the biggest fascists on the planet and a large number of people think they are doing some good.
