What should be our first message towards ET?
Inspired by Seth Shostak's talk about picking up messages from ET, I'd like to hear your ideas about what humanity's first radio message directed towards them should be.
Given the fact that an extraterrestrial civilization may be far more advanced than we are and perhaps already be aware of our existence just as we are aware of the ants walking around in the dirt what should we say when we first directly adress them?
The Voyager Golden Record and the Pioneer Plaques were designed to give some general information in case other forms of intelligence happen to come across them but if we were more certain that our message would be heard would be say something different?
I'm looking forward to your answers!
