It's actually agreed that we don't know much about the ground beneath us and volcanoes are mysterious places where aliens might practice snu-snu.
There's nothing anyone can do, that's the point of all the UFO sightings. If everyone (or anyone credible to everyone else) could explain them, nobody would care about them.
"ah it's just some alien ship, planning to abduct the poorly educated kid next door, who cares?" - "ah you're right, so what do you think will happen next in that dumb soap opera we watch everyday?"
Changed the title. Hope it's now more appealing.
