Human life as licking, eating, and drinking

On board Voyager 1 and Voyager 2 are 116 photographs and images depicting life on Earth. Carl Sagan led a committee to select the images. They are intended to communicate to aliens about human life. You can view all 116 in an imgur post. Included are mathematical formula, landscape photographs, breastfeeding, animals, food, ethnic diversity, buildings, and a letter in English from The U.S President Jimmy Carter. Interestingly, the nude image of a man and women were not included, and only a silhouette was allowed.
