No, it’s absence of evidence if you notice that we have ready access to high-resolution videos of innumerable rare events and elusive animals.

And yet the best footage of UFOs, ghosts, and Bigfoot still consists of some blurry, hazy, shiny, or dark blob smeared somewhere in a couple of frames of a shaky video at the absolute limit of the camera, exactly the same as forty years ago. Which is exactly what you’d expect to see if these were in fact normal things and optical artifacts that are perfectly explainable when they’re actually close enough to see.
