There is a Single Source of All Things. (As opposed to 0, 2, 3, ..., n, inf, etc. truly distinct (topologically completely disconnected) Sources.)

Other than the most extreme type of narcissist (which is intrinsically contradictory), all religions and/or philosophies and/or cults and/or investigations (including both The Science and all of legitimate science, math, information theory, etc.) all agree with that statement.

But that doesn't mean that there wasn't another entity (another Derivative of Source, possibly another spiritual entity or other physical entity ("The Aliens")) that modified (and/or created) the species that we call Homo Sapiens sapiens for their own purposes. While it's far from certain (plenty of reasonable doubts), there is a fair bit of evidence that supports that idea. Even the book we call "the bible" supports that statement substantially; especially if you look further afield than the "Canonical 66" (most Protestant versions) and/or use it as an archeological document rather than "Written by God (YHWH, the god of the Jews and/or Israelites) exactly and perfectly."

As far as I'm concerned, it is proper to be skeptical of your beliefs and other evidence that both supports and casts doubts on them, no matter what the "source" may be. Any other method of investigating evidence is nothing but dogma (AKA following your programming/brainwashing).

Once you truly appreciate that ALL THINGS come from Source (and what that implies), only then will the next veil be revealed. I don't know if that will be revealed in Disclosure, but there is a lot of stuff out there in the zeitgeist right now that is showing that quite dramatically.

Why THAT is (according to my investigation), is an evidence chain that will almost certainly not be in this movie.
