...aliens are tracking us. Not all of us, but a significant number of us. Abductions happen, and just as we tag animals in the wild to study their lives, aliens are tagging us too.
See these people with all the piercings in their ears, face, lips, and/or nose? Some of those are actually alien transmitters with which they study the person's movements. They have the technology to create false memories and make the person believe THEY chose to get their ear pierced again... they enjoy having all of these piercings... they experienced going to the "Piercing Pagoda" at the mall or "Old Stinky's Tattoo, Piercing and Botulism Emporium" and got this done.
Meanwhile, the aliens are watching... always watching...
