Interstellar meetings are bound to happen first with a large developmental gap. Applicable here is obviously us being the Cavedwellers, Sumerians, Azteks, Egyptians, whathaveyou. What happens? Astronauts appear as effectively gods, being literally superior beyond comprehension in every aspect. Religions sprout, sacrifices are made, wars fought...all because you thoughtlessly wanted to be nice and sey 'hello'. Self-knowledge is a prerequisite to fruitful, non-destructive communication between civilizations. The ability to comprehend the scientific technicalities is likewise necessary and we are just on the brink of that. There are (many) other requirements. Importantly, you have to be able to imagine a superior entity other than as playing the role of your "master".
