Maybe aliens are trying to contact us in a way they understand. SETI has been sending unconventional radio signals to random spots of the cosmos and waiting for a quick response. An extraterrestrial SETI might have launched ʻOumuamua a billion years ago hoping that it would be detected by alien life. I propose we find a cool Earth rock, launch it to the solar system Vega, and wait a couple billion years for an alien response.
