When believing in something, ask yourself why you believe in it.
I believe in Extraterrestrial Biological Entities. I don't usually call them "aliens" because it sounds so childish when you're talking to someone about this specific topic.
When I try and explain the existence of E.T's, it's because I believe strongly about them.
Why do I believe in them? Because there is proof. I've watched many movies, and videos, and read many articles. In the movies, they have real footage, and high up government officials who come out and talk about whats been going on. With everything that I learned, it all corresponds together. I want to share my knowledge with everyone because we all deserve to know what the illegal covert groups are hiding from us.
Here are some movies that I strongly recommend!
UNACKNOWLEDGED
SIRIUS (On Netflix)
Even if you are an amateur at this subject, these movies are perfect at explaining all of whats going on!
If you are an open minded person then you should definitely watch these documentaries, it has forever changed my way of thinking.
