If humanity possessed that type of technology we would have already have destroyed the planet

This is why the secret societies were created in the first place. To safegaurd technologies and truth about human mental abilities. These societies got drunk with that power and now think of themselves as elite, possibly gods. They were supposed to disclose these secrets when society could understand it but they decided humanity was too easily manipulatable and therefore cant be trusted. Thats why were in this mess because these secret groups have been poisoning the watersupply, figuratively and literally, and shaping a society that wants to be controlled so these groups never have to give up the secrets.
