The specter of UFOs and little green men visited Mexico City as lawmakers heard testimony from researchers suggesting the possibility that extraterrestrials might exist.
Should we ever discover real aliens, I'm confident they won't look like the stereotypical little green men that humanity has portrayed them as in popular culture for decades.
That's why they made them that way. Possible deniability.
Next you're gonna say the government wouldn't ever intentionally infect 1000000s of thousands of people with a virus and then spend decades studying the untreated ailments of it.
Or bombing their own towns.
Or mowing down with assault machine guns their own population.
Or poisoning their own drinking water.
Most likely the first evidence of extraterrestrial life will be mechanical (IE rovers, drones, landers) as they can survive indefinitely in space and are at the least risk of damage from the environment.
I could imagine that something like the slime mold could be an alien.
Single-celled amoebae can remember, make decisions and anticipate change, urging scientists to rethink intelligent behavior.
They are one of the oldest organism on planet (almost a billion years old) they have no brain but are able to plan, anticipate, remember and even share information. We can find them a bit everywhere on the planet and yet barely anyone knows about them.
If you ever encounter one they love oatmeal but hate salt.
