I have long thought that within a few generations of the establishment of a permanent colony on Mars, there will be stories about people who have encountered relict Martians in the outback. Or their ghosts. There's something about our nature as humans that leads us to experience the paranormal (or seek out the numinous). I posted the following in a bigfoot thread here about a year ago.

Many cultures around the world have legends of the hairy man or wild man of the woods:

In Basque mythology, they taught us things like agriculture and metal working. Some have suggested these legends represent remnants of ancient memories of our interactions with Neanderthals, Denisovans, etc.
As [another poster] points out, there is great cultural value to these stories, defining who a people are and where they come from. For many of us modern Westerners, unfortunately, we've lost our defining stories, and the wodwos have retreated to the far forests and river bottoms. Legend and myth simply means untrue things to us rather than being the defining stories of our cultures. The Sacred Groves have been emptied of their power as are many of the churches of our traditional religions; so some of us find solace in UFOs, or the paranormal, or cryptids.
The search for Bigfoot is, therefore, a search for meaning; but the True Believers need to ask themselves: if you grab his foot and hold on, will he tell us your heavenly names or greet you with silence? Do you really want to find what you're looking for?
