From Wikipedia (as of Jan 23, 2017):
Ringwoodite is a high-pressure phase of Mg2SiO4 formed at high temperatures and pressures of the Earth’s mantle between 525 and 660 km (326 and 410 mi) depth. It is polymorphous with the olivine phase forsterite (a magnesiumironsilicate).
Combined with evidence of its occurrence deep in the Earth’s mantle, this suggests that there is from one to three times the world ocean‘s equivalent of water inthe mantle transition zone from 410 to 660 km deep.
Ringwoodite is right up there with dried blood and soft flesh on dinosaur bones, when it comes to verifying the Noahic account of the Flood.
Now, materialist atheistic philosophers have no interest in pointing out the faults of materialistic atheism, and how it simply doesn’t match up with reality.
Christian do, and Christians should do the spadework to get the word out.
The power of the mainstream media is being cut out.
Christians should seize the opportunity to rise to a position of authority. Authority comes from accepting responsibility to speak the truth, clear and powerful.
And a rock full of water is a great way to start!
