Not too sure about this one. In the beginning of the video it says that E.T.s were traveling through space and had engine trouble and then fell to Earth. Not sure how that would be possible if there was a firmament. These are the questions that first come to mind...

1. If there is a firmament, how are E.T.s able to pass through it and "fall to Earth"?
2. If there is a firmament, and E.T.s can pass through it, does it require a type of signature to do so?
3. Is space fake in terms of how we have been taught?
4. Do E.T.s and how our world perceives them actually exist?
5. Is this video bs?

Question 1 being the most prominent. So much information out there that they tend to put holes in other theories.
