Is Gobekli Tepi now the oldest man made structure ever discovered?

Answer 1

Göbekli Tepe is not the oldest man-made structure. Tell Qaramel in Syria is older, as is Boncuklu Tarla in Turkey. If you consider a grave or tomb to be a structure though, there are loads of sites with graves that predate even these places by thousands of years. Anzick-1 is a good example of a burial from North America that is thousands of years older than Göbekli Tepe, and there are many caves in with evidence of humans using them as a kind of structure even as far back as the Middle Stone Age around 100,000 years ago.
