What if Earth is like one of those uncontacted tribes in South America, like the whole Galaxy knows we're here but they've agreed not to contact us until we figure it out for ourselves.

Like say ufo's are real but it's just like when those tribes see planes flying by, they freak out and run around telling the whole tribe, they probably have wild stories about what they are and where they come from too.

Extraterrestrials see us like we see those tribes.
