Some cryptid enthusiasts believe that the Ningen is a yet-undiscovered species. Given the vast, unexplored depths of the oceans, they argue it’s possible some unknown aquatic life forms have evaded human discovery. After all, there are strange creatures in nature all around the world.
Skeptics argue that you can often attribute the supposed sightings to floating icebergs, large aquatic animals or even tricks of the light.
While you’d struggle to find text on international journals about the Ningen, you might find news outlets occasionally discussing the validity of sightings. For example, a Daily Star article about a supposed sighting featured a quote from Phil Poling, who breaks down urban legends on his Paranormal Breakdown blog.
“The quality of the video is highly suspect as it’s highly compressed,” he says. “The blotchy pixelation may have been used to cover up bad CGI work.”
