In a potential landmark discovery, scientists using the James Webb Space Telescope have obtained what they call the strongest signs yet of possible life beyond our solar system, detecting in an alien planet’s atmosphere the chemical fingerprints of gases that on Earth are produced only by biological processes.
Finding bacterial would be super cool, we could learn a whole lot from that! But if we do find complex alien life, multicellular life or something like animals, well that’s a really, incredibly bad sign.
That suggests that complex life is common in the universe. And if complex life is common, intelligent life should be common. And if intelligent life should be common, but isn’t (because where are they all?), that says bad things about the success and survival rates of intelligent species.
