Is There a Correlation Between Missing Persons in the Woods and Aliens?

There's a theory that if you look at a map of cave system in the united states, like there are people out there who also go missing, oddly often next to caves. And somehow that means cannibals. Could be really bad people hiding in the woods and doing bad things. People have referred to them as stair stairways to hell. They might actually be portals directly to hell. Some think that it could be a spiritual portal and lead to other dimensions,. because it really leads to nothing that we can see. That's a alot people whove approached these stairs say that they have felt dread, nausea, fear, just total danger.
