“The limestone bed dates back to nearly 300 years after Jesus‘ death.”
That’s some young limestone.
Yes, a geologic miracle.
If it’s 1700 years old, that would date it to about the time that Helena (Constantine’s mother) went to the Holy Land to identify sites associated with the life of Jesus. No one knew where Joseph of Arimathea’s tomb was so they obligingly carved a fresh tomb to show to Helena as the right one.
No kidding. I would say that is the youngest limestone ever studied (I am a Geologist).
