Back in 1977, NASA sent out two Voyager spacecrafts that were stocked up with items from Earth as a way to convey human life to anyone -or anything- that came across them.

Included in these spacecrafts were two phonograph records that played a culmination of sounds that represented the human race and Earth itself, and they have now been uploaded onto the NASA SoundCloud.

The records include greetings from known languages and more random sound selections such as infants crying, mother’s kissing, crickets, frogs, wind, rain and surf.

Listen to both records below.
