People here are so on my wavelength. Sometimes I dabble in writing short sci-fi stories and as soon as I read this I started a near future story where a tribe at risk of extinction from an impending earthquake must be saved without triggering the problems previous people had making first contact. At the same time, an ET civilization is using the same kind of methods and a much more advanced technological level (through methods like DMT elves and seizures), to contact the technology people of the new world order (that is the group preserving the culture at risk of extinction) and teach them enough to get off the planet before it's hit by an asteroid (or whatever). I think the right way to contact them would be to use mechanical bugs to infiltrate their society, and learn their language and social structure. Then, in the modality that the shaman of the tribe trances in, contact only the shaman, and in their language and their mythological mode of thinking, convey what you need too. Then, teach the shaman 'magic' in the guise of technology that will allow him to convince the tribe and convince him of your power and authenticity. Particularly effective would be to make another tribesman sick with some disease and give the shaman the medication to cure the disease. Then, let them have as much of their way of life as possible after you did whatever you needed to do to prevent them from dying off like they would of without your help. You should only make contact in cases where the tribe is at great risk without it.
