spaceflight, Why was the Search for #Extraterrestrial Intelligence (#SETI) 👽 unsuccessful so far ?
#Life 🦠 appeared pretty much as soon as it could, right when the #oceans formed and our #planet stopped being a molten 🌋 hellscape. That might have been as early as 3.7 billion years ago. But #intelligent life appeared basically yesterday—what we identify as anatomically modern humans arose about 120,000 years ago. https://arstechnica.com/space/2023/05/were-essentially-alone-in-the-universe-and-thats-ok
