Hey - What if the original 'temple' at Gobekli Tepe did have a roof (probably wooden logs) covered with soil and grass - after all the site is 'just below the brow of the hill' - so that it was then 'underground - inside the womb-shaped hill - for ritualistic reasons. Then - after a period of disuse and probably during an earthquake, the heavily-loaded roof fell in, burying the 'temple'. On that basis, it's not necessary to invoke the idea that the inhabitants 'buried' their temple - possibly because it wasn't 'delivering the goods' any more...! The fact that it now has to be unearthed is probably down to natural / geological events...
