One thing I'm pretty sure about is that if extraterrestrials do contact us, it won't be with a landing party like those of European explorers. They would make radio contact first.
We do seem to be getting treated similarly to the way we treat uncontacted tribes - study but don't interfere. There may be several different species coming here for different reasons, but all prohibited from formal contact. Some may be here for anthropology, and others to make entertainment out of our foolishness. There may be some here hoping to get salvage rights if they prevent a nuclear war. Others may be here to make sure we never leave our solar system until our movies are about interplanetary cooperation rather than Star Wars.
I strongly suspect that one thing they have in common is getting through their agricultural phases without letting economic inequality rule society before making it even more dangerous with technology.
