Deflating the power of secret societies

Will the truth about the origin of human civilizations ever surface, and if so how will we recognize it among the untruths and half truths of the specialists. Perhaps bias is built into human nature in service to the will-to power?

My hypothesis is that the ancient Sumerian-Egyptian civilizations were not the origin of the Indo-European civilization, but that it was late migrating Cro Magnons or Proto-Indo-Europeans who were the origin of both the Indo-European and Sumerian civilizations. How the geographical migrations took place is not clear, from the North, from East to West, or some combination of these?

If Cro Magnons founded these ancient civilizations then the myths and symbols of these civilizations are untrue or inaccurate.  For example, occult knowledge in formerly secret societies has said that these civilizations were founded by amphibian-like beings from the Sirius star system.

Here is why it matters.  If we are trying to decentralize the world to save the world, this can mean decentralizing the secret society-occult structure, which is more or less based in this Sumerian-Egyptian-Sirius myth---that is, the Neo-Platonic-Gnostic-Hermetic-Kabbalistic-Rosicrucian-Masonic traditions follow this mythology. 

The truth can deflate the power of these secret societies, and secret societies and occult religions seem to be more, or less, involved in imperialism and supremacism in the world today.
