I’ve been watching and listening to unhealthy amounts of fermi paradox theories recently and they always talk about how we can’t see any signs of intelligent life in our universe but if our technology only sees light that traveled from millions and possibly billons of years ago how do we know if they’re actually not there?

Might be a stupid question, that’s why I’m asking it on reddit instead of my teacher.
