The People came through space from their Home World. They were looking for minerals and metals not readily available on the Home World. They invaded our Earth. They did not come with violence and conquering armies. They did not drop bombs. They did not fill our skies with strange looking space ships. Strange looking beings aren't roaming our streets at night. The invasion started not yesterday but 3,700 years ago. They introduced invasive species. And they are still with us. We see them every day. We see them every day and we have no idea that they are here. They are here to exploit the mineral riches of our world.
