The most ancient statue crafted by humans that has ever been found comes from Germany - the Venus of Hohle Fels.

The statue depicts a female body with luscious curves, which according to experts symbolizes the goddess of fertility.
The oldest shoe found by archaeologists comes from a cave in Armenia and is 5500 years old. It was made quite skillfully from leather and bears a close resemblance to today's moccasins. It was packed with grass on the inside to be more comfortable for the owner, whose foot was about a size 7 US.

The oldest bathroom is located in the ancient Turkish city of Ephesus. According to scientists, the toilets are 2000 years old. The remarkable thing was that these were toilets with running water because they were built in an area where water flowed constantly and washed away the waste.
They were designated for public use, as part of the Scholastica Baths, which the ancient inhabitants of Ephesus paid taxes for.
Passing down cooking recipes from generation to generation gains a whole new meaning when you find a recipe 4000 years old. The earliest recipe was found in the lands of ancient Babylon, carved onto a tile.
