Voyager Golden Records

In 1977 NASA launched two space crafts called the Voyager 1 and Voyager 2. Aboard them both were phonograph records called the Golden records. They contain a range of different sounds and images which have been chosen to show and portray life and culture on Earth.They are intended for any intelligence from extraterrestrial life form or even future humans who may find them.

A lot of the stuff on the discs are out of date and of no interest now but the content is still key and on the right lines of the message I think I would like to send on the modernised version. I myself don't understand the point of using languages since if found by extraterrestrials how do we even know they speak a language?Even if the discs are found by a future human race, languages may have changed by then. Being the reason I think its best to just stick to images, something which everyone can relate to easier.
