The limestone the builders didn't pay attention to became a stumbling block

The geological society of America says, " Karst geology played a major role in Jerusalem's selection by David for his capital," Bramnik says. It proved to be a wise decision. One of David's successors, King Hezekiah, watched as the warlike Assyrian horde, a group of vastly superior warriors toppled city after city in the region. Fearing that they'd soon come for Jerusalem, he too took advantage of the limestone bedrock and dug a 550 meter-long (1804 feet) tunnel that rerouted the spring's water inside the city's fortified walls."

  So were there tombs with limestone stones blocking the doorway?

 Wikipedia article on limestone says," Most limestone is composed of skeletal fragments of marine organisms such as coral or foraminifera."
 Hence life on Earth is much older than the 6000 years the Babble suggests. Check mate, get past that one Jesus. The limestone the builders rejected becomes a stumbling block for Christians that they can not roll out the way. 


How about this for a scenario: Maybe when the tomb diggers mined out the tomb, where Jesus ended up, they didn't realize that there was a sink hole a few inches under the floor of the tomb. On the day that Jesus died there were lots of people mining away at the limestone / chalk / gypsum forming tombs. There was an earthquake which made them panic and leave their work.With reference to Matthew 27v52; Visitors to Jerusalem for the passover saw the miners covered in white chalk dust and mistakenly assumed they were ghosts risen from the dead (As you do)   Later Jesus body was placed in the tomb and it was sealed with a round limestone stone. Another coincidental earthquake then happened which caused the now weakened floor of J.C's tomb to collapse. Jesus' body fell down the sink hole and then was flushed away by an underground stream. The earthquake also made the stone by the tomb entrance fall over. The disciple who looked into the tomb either couldn't see the hole in the dark or maybe some stone from the roof fell in afterwards and blocked the hole from view?  The disciples were so surprised by the shock of the earthquake and the absence of the body that they hallucinate, imagining that they see Jesus.
 However if there was a hole in the floor of the tomb maybe  the council indirectly found out and either sealed the tomb & covered it = so it is now hidden or perhaps they had the hold repaired.
A sort of mix of "Finding Nemo" and "Flushed away" 

[ Virutally impossible that  a sink hole would have formed there = its a miracle. But maybe millions of years ago there was a lot of water there ]
