There is an article in Discover Magazine about the idea that aliens are living amongst us. I don't mean as in humans that may get here in the back of a semi from our southern border or from those who may land and clear immigration and customs at our airports, but as in creatures from out there.

Now these aliens don't take the form of little green men, or ET, or even Mork from Mork and Mindy.

These aliens may be little tiny life forms with just RNA. They may be at the bottom of the sea, in a crevice in the desert, or maybe living in an unrecognized form in our refrigerator.

They are there, waiting, one supposes, for the opportunity to spring on all us DNA creatures and take over.

I guess they are patient.

But think about it. Suppose the right opportunity comes along and they strike. Life is fragile. Human life is the most fragile.

Plants and animals at least can exist in their daily lives and to what comes naturally to them. They don't have to deal with matters that concern humans. Matters of friendship and trust and love and hurt. Oh, sure, the higher mammals do have some degree of feeling, but let's face it: if Bonzo the Gorilla is tossed over for King Kong, he just shrugs his ape shoulders and grabs the next best looking girly primate he can.

Or he grabs himself, and is happy.

No harm, no foul.

I think this may be the big threat. While we are looking for Osama, the human race will be done in by simple RNA creatures who learn that DNA based humans are all too prone to break down on feelings.

So if Discover Magazine is right, and if they are lurking in our crispers, we are sitting ducks, because humans are so weak.
