Hello, I was doing some research about The Great Filter theory because it interests me. But there is something I can’t find answer to. So I hope you will help me clear my head with this. What would mean if some inteligent form of life visited us? Like bilion or more years old civilization from the other end of the galaxy. Would that mean that filter is in front of us or behind us? I can’t get my head around it..

Well, if they told us there are a bunch of planets with intelligent life like ours that are stuck in their solar system, that would imply the filter is ahead of us. Intelligent life happens a lot, but interstellar transit is hard to achieve, and that’s the filter.
If they tell us we are the first other intelligent life they’ve met after a lot of exploring, that means we’re probably past the filter, one of the few survivors.
If they say there are a ton of other civilizations that can travel interstellar distances, we can’t conclude much. Maybe the filter doesn’t exist in that case, or still lies ahead of everyone.
