There’s also the Dark Forest hypothesis - the idea that maybe many alien civilizations exist out there but stay silent because revealing themselves would make them targets/prey to a more high-tech hostile civilization.
Maybe we aren’t the first, maybe we aren’t the last. What if there is other intelligent life on other planets, but just because of the distance their signals have not managed to come to us and our signals haven’t managed to get to them yet. That should be fairly possible simply because of the how big the universe is right?
This is just arrogance.
We have only been announcing our intelligence for 100 years. It takes 100,000 years just to cross our galaxy. No-one knows we are here yet.
