There are billions of potentially habitable planets in the Milky Way galaxy
Well, that’s it then, all the tales of aliens visiting our planet must be true. Out of all those planets, some must have the technology to travel thousands of light-years to come play hide and go seek with the most unsophisticated of our species.

It’s good to know that those billions of possible life-supporting planets, their potential life-forms and their evolutionary paths conform strictly to what we see here on Earth (carbon based life-forms dependent on water). Otherwise this alien-life-finding business might have been a lot more complicated.
