Kurt Schreiber Posted about 3 years ago What should be our first message towards ET? Good point, but they would only be able to decipher our languages if they communicated in a similar fashion to us. Even if they evolved on an Earth like planet, it is still possible that they don't use language as a way to communicate. If they have evolved on a planet completely unlike Earth it is possible that they have never encountered language before, so if they encounter our radio and TV signals they may have no idea how to decipher it because they have no idea what it is. Or they could be so many millions of years advanced, language is a primitive form of communication to them so they wouldn't even bother making contact with us.
