Reddit - Staircases in the Woods

There are mysterious sets of stairs that were just built so long ago archaeologists don't even know really what came from them. The a over all theme is that people are very disturbed every time they find these stairs. People claim to have seen them all over the world in multiple conditions, made from multiple materials. Sometimes theyre brick, sometimes are metal, sometimes ar stone. And sometimes they look like they're abandoned, like dirty ruins. But other times they look brand new and modern and clean, without any like, bird poop or dirt on them.
