Cave drawings is the obvious solution, but if you are looking for a structure, then Göbekli Tepe is the answer.Göbekli Tepe is the world's oldest temple, dating back to 9,000 BC. Not only does it predate Stone Henge and the Fertile Crescent by many thousands of years, but also predates pottery, metallurgy, writing, the wheel, agriculture, and animal husbandry.
Approximately 3.8 billion years old! These were simple single cell organisms. Complex life did not appear until 1.8-2 billion years later, these still being just tiny multi-celled organisms. Vertebrates did not appear on the scene until about 525 million years ago.
That depend on your religion. Some religions believe that people were. But if you go for evolution, then its single celled organisms.
