Where are the tools that carved the high relief sculptures at Gobekli Tepe, around 12,000 years ago?

Where are the high relief carvings that predate Gobekli Tepe, which served as the skill development toward it?

And we don't need to go nearly that far back to notice lack of ancient metal that had to exist, given what it accomplished.

Metal disintegrates fast. Megalithic evidence, at minimum and across history, implies a woefully incomplete archaeological record.
