An alternative scenario to this Galactic Federation claim I've run across is from this "reptiliandude" guy. He claims that the real bad guys here are the Consortium and the primary shareholder race is the "Kayeen" (obviously derived from Cain) who are humanoid Nord-like who pose as gods and are the backers of the Deep State cult. RD claims that his "reptilian" race worships God and were attacked by Kayeen hybrids created on Earth and so the reptilian alliance dropped a meteor 13,000 years ago to attack the Kayeen. (cf. Great Flood) But then God (appearing as a "burning tree") and the Assembly of the Universe who follows Him intervened in the war to stop both sides and force them to repair earth as the Consortium.

Gradually the Consortium began to forget about God's intervention and saw it as mythical so the Kayeen and the other races began to treat humans as a genetic lab where they sell our immunities to other species and the Kayeen use humans as a replacement body because their own are so genetically damaged by their own experiments. Anyway, different perspective. Not sure how it melds with your claims from David Icke/Corey Goode.
