Time travelers are responsible for what we know as the Mandela Effect.  It IS a factual happening, and it appears someone is effecting even more changes that way to our timeline here.  There is truly some cause for concern, but far more capable people than just US are working on that end of things.  Right now, the prime focus is to wake up humanity to understand that they have already been long enslaved as a race.  We have allies and actually stellar ancestors that want to see this stopped.  It's a complicated history that we have, to say the very least. But even the aliens believe that far too many humans are religiously groomed to do anything but sit on their knees and wait for someone else to deliver them.  That's NOT going to happen like that.  If WE don't evolve the brains and spines to stand up and *start* taking our own responsibilities seriously and *start* taking our own control back... It is ludicrous to expect an interstellar or interdimensional invasion, since that happened over 300,000 of our years ago, and the Anunnaki, reptilians (SOME factions, not ALL), and a number of other criminally inclined races (bases in Antarctica) have been here longer than WE have and have dumbed down the seed races that the Pleiadians planted here (US).  As we start showing the universe that we ARE a worthy, growing race (in control of OURSELVES) we get to join up with the rest of the mulitverse and discover what freedom is truly all about.  If not... this will all be proclaimed a "failed experiment" and a few meteors get introduced to our planet, and they will start from scratch once again.  I really have to get a lot of this into a decent video, but right now, I want more "proof" from them, to show people that this isn't just another conspiracy addict's silly, woo-woo dreams.  We're kind of working that out now.
