We don't have to look beyond Earth to find other life forms, though they may well also exist out there. There are some pretty strange life forms all around us. If they do exist beyond Earth, it is my guess that they be stranger than the strangest of creatures from the deepest depths of the Earth's oceans, stranger than thoses strange organisms that can exist on Earth in near boiling water, even stranger than that thing that is growing at the bottom of my neighbor's industrial waste bin (dumpster).
What I doubt is whether any life forms we may or may not find beyond Earth, assuming they don't find us first, would be anything even remotely like ourselves. Of course I could be wrong. Perhaps that fellow I was talking to yesterday at Miss Pixie's New Age Wonder Store (for budding space cadets) really did grow up in a dumpster on planet Xcykhjeepfiinz, as he claimed.
Now I have to be going. I am determined to finish teaching that hairy thing, at the bottom of my Christmas coffee cup, how to speak English before August.
