After the WWII they managed to create lots of clones. These clones were ordered to mate and pretend to be families with children. Right now anybody you meet might be a clone. This is what Hollywood was showing in their sci-fi movies since the beginning. Movies like Invasion of the Body Snatchers, or They Live, or even The Thing just to name the most famous ones. The plot is always identical, for some reason humanity is being replaced by humanoids who pretend to be humans in order to eliminate real humans. I don't know if there are still real people here on Voat, but it looks strange that nobody takes the clones conspiracy seriously.
