I like the theory of quantum entanglement communication being possible (which would in theory be instant - we don't even understand why yet but have observed the effect) BUT even then, initial contact would have to be non-quantum to set up any such quantum entanglement, as I understand it. The "entanglement" has to happen at the same location, but then the particles remain in sync no matter how far you move them from each other (in theory, including lightyears apart). But yeah... The issue is how do you make first contact.

That reminds me of the Futurama episode when Earth is invaded in the year 3000 because a TV program in 1999 got cut off and the aliens watching it were just over a thousand light years away. Fry asks how they can even know about a show from a thousand years ago
