I'm a bit surprised that no one's responded to this yet.
I agree with you, the only way disclosure will ever happen is if aliens/UFOs landed in every major city and a lot of people witnessed it. That’s the only way the government wouldn't be able to deny it. If the government did disclose the existence of aliens, I would be afraid...
VERY afraid.
One day disclosure will happen, the truth will only stay hidden for so long. Whether or not it’s in our lifetime is another question, however, I do find it odd and a bit disturbing that the pope has officially declared that it is OK to believe in aliens.
