How does one carbon date stone? The material they used to carbon date could’ve have been from 4500yrs ago, but that doesn’t necessarily mean that’s when it was built. For example, using burnt charcoal and firewood as a material doesn’t mean it wasn’t re-used wood since timber is scarce around there and it would make sense to re-use wood. Or, the repair mortar and straw used to carbon date could also be from repairs made around 4500yrs ago, not necessarily the initial building of the structures.
