There’s a report out of San Francisco that says the aliens may already be here:
“The intriguing possibility is they are, in fact, here, but we just don’t know it,” said Andrew Fraknoi, the emeritus chairman of the astronomy department at Foothill College who recently taught a course on aliens at the University of San Francisco’s Fromm Institute and believes space aliens could very well be microscopic or unrecognizable as a life-form.

While microscopic life is a possibility, I’m thinking there might be a little more to it than that. I mean, if a fully grown, full-size, two-meter tall alien showed up in San Francisco, would anyone really notice?
Perhaps the Fermi Paradox isn’t a paradox after all.

I forget where I saw it, it might have been a series by Craig Alanson that starts with Columbus Day, but it’s the best explanation for the Fermi Paradox.
Imagine a house with a bunch of monkeys with firearms and explosives going crazy inside.

The way to tell if they’re aliens in San Francisco? Their poop in the streets doesn’t smell the same. Sorta flowery.
I heard it posited that Octupi could be aliens.
The article’s quote is from a guy named Fraknoi. He’s obviously taunting us when he says aliens may be here already.
Just look outside any Lowes out west, aliens all over the place looking for day work.
San Francisco is indeed full of space aliens…and has been from the mid-sixties to today.
San Francisco California….you will never find a more wretched hive of scum and villainy. We must be cautious.
The Hitch-hikers Guide to the Galaxy recommended landing in Central Park in NYC. The natives will ignore you, and the more you appear different from humans, the more determined they will be to ignore you.
