It may seem like I’m poking fun, but I have all the time in the world for the types of speculations described in this piece. In virtually every case, the scientists listed as many natural phenomena—both known and speculative—as possible to explain the inexplicable, prior to invoking alien involvement.

Scientists should be allowed to posit these types of speculations, and possibilities must remain possibilities until scientists can rule them out. Because one day, that strange thing we detect might actually be aliens.
