In my research, I find the notion of the existence of these “higher” beings to be so strongly supported that they cannot be dismissed out of hand like the {mainstream} always does.

Like you say, the Sumerians spoke of their Annunaki, the Hebrews spoke of their Anakim (and the related Nephilim), the sub-continental Indians and their “Aryan Brahmin” foundational beliefs, the South American empires recorded their tales of Quetzalcoatl, the tall bearded white skinned “god” who appeared on their coasts one day and promised to return, these motifs or themes exist in ALL ancient societies which touched “pre-history” (as the {mainstream} dubs anything prior to “writing”).

All the variations echo the same core, a “magic”/“godlike”/“sufficiently technologically advanced” group of (seemingly white people but that shouldn’t necessarily be extrapolated to any further conclusions) “Travelers”.

So:

1. Why were they “traveling” to basically every culture on earth?

2. Where did they come from?

3. What was their “technology” based on, considering we don’t see evidence of skyscrapers or computers or whatever we normally would recognize as “technology”

I think 1 is answered more cogently by “a great society on Earth, which suffered unimaginable cataclysm (likely passed on to all their descendant cultures in the “Great Flood” motif). This cataclysm was (likely) centered on their home-land, and drove their peoples off in all directions (the Ur-Diaspora or Proto-Diaspora which we again see echoed in most all founding myths).

Let’s imagine they were just normal humans -

[less assumptions which are not explicitly demonstrated - HOWEVER there seems to be much evidence which supports the notion they were “giants” compared to the peoples they settled with, but again, beyond a few crazy skeletons and cultural “myths” this notion will just become a vector for attack on the idea without a long detour into other evidence, but frankly I take this evidence to indicate they were capable of “genetic engineering”, which is again a motif echoed in basically EVERY cultural foundation myth]

but they had more time to “advance” in their various disciplines (look how far we’ve come in just ~200 years in terms of “tech”, this culture would have likely had far longer).

Basically the classic “Atlantis” story.

So “something other than humans” is plausible, I just feel like it introduces claims which don’t need to be made, which often require a long tangent and reference to materials (cultural Holy Books) which many will dismiss out of hand, and which many disingenuous critics will latch onto as a perceived “weakness” in the argument { i.e. “mUh aNciEnT ALiEnZ”}

For the second point, there are some good attempts at finding an answer. The “Eye of the Sahara” being reasonable, the Mid-Atlantic Ridge / Azore Islands hypothesis being reasonable, a North American or Pacific Ocean empire (of the Asian phenotype) seemingly being supported by some of the evidence. That one’s harder to answer, given the utterly catastrophic effects of whatever was powerful enough to set off the Younger Dryas period, and ending the ice age overnight/causing climate fuckery that the UN and deepstate can only fantasize about.

To the last question, of their technology, while I think it’s entirely plausible they had much the same technical knowledge as we think we have today, they also operated in domains of “science” and “technology” which today our {mainstream} UTTERLY REJECTS. I am of course talking about the Forgotten Technology within Man:

c/HumanPotenial

Imagine a society where everyone was trained up in the Lost Art which today exists in as many different forms as there are cultures. The science of Chi/Ki/Prana/LifeForce/“bioelectricity and biomagnetism” as our modern culture might label it, if it were ever willing to remove its blinders.

Hundreds of thousands or millions of people, literally psychically working towards a common goal? I think that kind of power or “technology” would be capable of, effectively, transmuting reality.

Edit: this comment itself is starting to tangent, but one interesting addendum to the notion of this “Forgotten Technology” - many untrained people are capable of small flashes of use of this technology as seen in the huge array of “ESP”/“Para-“ research. Very few trained people are capable of acts which defy “reason”, and effectively qualify as “magic” according to our {mainstream} understanding, some of which I’ve tried to collect at that .Win

Now just apply that paradigm to our modern world. We are kept perpetually bathed in EMF radiation (plausibly affecting this “technology” of “bioelectromagnetism”). We are kept stupefied on drugs and bread and circuses. We are kept ignorant of this technology through active suppression (“omg you believe that woo-woo? Let me guess, you own a collection of crystals and think the earth is flat?!?!”).

And most vitally our EMOTIONS, ATTENTION, and ENERGY are directed by vile abominations of the Lowest Order. 9/11, Covid, School shootings, you name it. All the bad is being fed into us 24/7 365 if they have their way. Just imagine effect that could have on the WORLD ITSELF, in the paradigm that I propose best fits the evidence. Clears up some crazy “why”s in my opinion!
