1. This video was supposedly taken by a robotic camera while surveying an old oil tanker. A school of fish briefly swims in front of the camera and suddenly one of the fish gets nailed by a spear in front of the camera. Something fast swims by to collect the fish shortly after. Many people believe that this video demonstrates the possibility of some kind of advanced sea creature who uses tools to hunt. After all, there’s no reason for a person to be this far underwater hunting with a spear, and whatever moves in front of the camera is too fast to be a person. Of course, the obvious answer is CGI, but I would still like to get your thoughts.
