I still remember a story my teacher told me when I was young.

2 white guys come to a mountain. The villagers said that the mountain is haunted by ghosts. The villagers tried, unsuccessfully, to prevent the tourists from going up the mountain. The tourists went up, never to be heard from again. Or quite like that.

I supposed some high tech embassy start getting involved. Scientists then examine the mountain.

They didn’t find any ghosts. However, they did find that the scientists are death, due to gas poisoning.

There isn’t a ghost there. But there was something there.
