1. What is the difference between "speculations" and "conspiracies"? (Circular argument) Some part of the definition for the term, "conspiracy", covers "speculation".
2. The example of the Snowden episode tells us, the audience and readers, that it is possible for agencies to collaborate keeping things hidden. This is a proven fact.
3. Just because it derives from "YouTube" does not discredit the source or evidence. This is a fallacy, it is called: Genetic Fallacy. For instance; there are videos, on Youtube, concerning Snowden.
4. Therefore, there are some things on YouTube which could be proven to be based on empirical evidence and factual information. If we believe in our five senses. Nevertheless, Rene Descarte came up with a thesis to critique the previous senses. However, I doubt that it would discredit the video evidence of the "men in black":
"The real Men in black caught on tape?" by StewieBlackOps
(Note: this should be considered separate evidence because the Apollo 20 video could be a hoax while the "men in black" video could be real)
5. Therefore, just because NASA says the Apollo 17-20 missions were cancelled does not mean that it never occurred. The previous links I gave presented several whistleblowers. Also, it could also be the case that the missions were renamed something else within NASA circles and operations. Also, the Soviet Union is also known to hide secrets from their public. For example, the biological and chemical warfare programs.
6. Just because there was inaction by the gov. does not mean that the info is or was false. It could be that it was allowed in the open because if they acted upon it,it would then indicate that there was a cover-up. In other words, too many people know about this person or individual and if they physically acted then it would alarm others that the info was truthful.
7. The argument I presented, along with Semjase, is called an inductive argument. Obviously, it is not deductive because we do not have physical proof to have a solid conclusion. An inductive argument is in the realm of "speculations". Also, my own personal experiences concerning UFO crafts could not be proven because I never had a video recorder with me to provide evidence plus it could be possible that these crafts are manned by humans from Earth and even the NAZI faction which survived(another theory). Yes, there is actual proof of craft engineered by the NAZIs.
8. However; I will admit that it is possible that the Apollo 20 mission, or the mission recording a crashed ship on the moon, could be a hoax. I will admit that because I also have several questions concerning the video(or evidence).
Here I prove that I am an agnostic concerning the video. I also have several doubts and questions concerning the video submitted by Semjase.
9. Let us not disprove the evidence based on the source but let's evaluate it. It could be that some things are true and some things are false concerning E.T.s. Let us evaluate the premises and conclusion.
