I know it's popular in certain circles to romanticize the noble savage, but, IMO, doing so is to indulge in extreme fantasy. The indigenous magic fails because their gods and power is all low level stuff. The primitives are simpletons and they align with/co-create simpleton "gods". They don't "live in harmony with nature", etc, etc because they are wise and gentle. They do so because they are too stupid to accomplish what they would if they could. They are closer to animals than creative adventuresome humans; spending their entire lives doing things they way they have always been done in the same little patch of jungle they have lived in from time immemorial. They war and kill, take slaves, damage the environment, etc. They just do it on a less grand scale because they are not smart enough to figure out how to do it bigger. It's not a matter of moral superiority.
As for aliens, not saying this is what it is; just something that an open minded skeptic must consider - the UFOs are US military special weapons R&D...... So what if a certain team developed the technological ability to project an image (maybe like a holograph) that fighter pilots would see and chase like a cat on a laser pointer and simultaneously could hack radar systems, etc such that it would appear as if the image was a material object being tracked by all of that tech? The best way to test its effects would be to keep it totally secret and then see what happens when applied to our own personnel and technology. That way the effects could be studied in depth. This would be a powerful weapon in the event of a real war. Some of the reported psychological effects are just typical PTSD from mind-blown/paradigm shifted syndrome as opposed to aliens intelligences deliberately altering perceptions. Also, better to let people believe in real UFOs than to reveal the secret weapons program once the weapons system has been tested and the testing has leaked out. I mean what else are you going to do?
So called "alien abductions" are probably a whole different class of event(s); a bucket containing a lot of slop like hypnogogic imagery, sleep paralysis, misinterpretation of real OBEs, epilepsy, effects of intoxication, schizophrenia, borderline personality disorder, outright lies and hoaxes, urban myths and so on and so forth. At least these explanations deserve serious consideration.
The only expanded consciousness phenomena we can be certain are real - at least some times - are precognition, OBEs, NDEs, Life after death/ADCs and psi (and probably reincarnation). There's way too much noise and confusion around all the rest; along with viable very normal explanations.
