Contacting alien civilizations

Austrian astronomer Joseph Johann Von Littrow proposed early in the 19th century that people should send a message to alien civilizations to let them know we are here.

He proposed to dig trenches configured in large geometric patterns in the Sahara Desert, fill them with kerosene and light them. His idea never came to fruition, but we haven't stopped our attempts to contact extraterrestrial life.
