In 2008, Klaus Schmidt discovered a site in Turkey that is believed to be the first temple ever assembled by mankind. Known as the Göbekli Tepe, this massive carved stone structure date backs to 11,000 BCE and predate Stonehenge by 6,000 years. The temple was built before the advent of metal tools or even pottery.
Essentially a set of T-shaped pillars and stone rings, these structures are adorned with crude drawings of various animals including lions and spiders. The site has already provided new information about the formation of societal evolution. But what exactly those drawings mean and the specific function of the temple is still undetermined.
