It was space aliens. I am such a conspiracy theory nut, I just blame all unexplained things on space aliens since their technology can't be explained anyway.

Are ya shure? How do you know? Have you conclusively ruled out a common, average, run-of-the-mill, garden variety methane hydrate ejecta-bolide?

Why do you insist on jumping to the conclusion of such technical, far-fetched, complicated explanation rather than simple ordinary natural phenomena? As a student of the Sherlock Holmes school of Occam's Razor, I prefer the MHEB theory. You know what his attitude on criminolgoy is: once you've ruled out the most complicated conclusions in decending order, the simplest explanation, however likely it may be, MUST be the truth.
