Food for thought article, neither is it expected to tell the full truth. There are many lies taught about the nature of the planet, the further back in historic/ancient writing you go, the more information you can uncover. What the earth does NOT appear to be is a orb spinning through space around the sun. What does appear more likely is something along the lines of the image below.
Jeremiah 16:19 | O LORD, my strength, and my fortress, and my refuge in the day of affliction, the Gentiles shall come unto thee from the ends of the earth, and shall say, Surely our fathers have inherited lies, vanity, and things wherein there is no profit.

A reservoir of water three times the volume of all the oceans has been discovered deep beneath the Earth’s surface. The finding could help explain where Earth’s seas came from.
The water is hidden inside a blue rock called ringwoodite that lies 700 kilometres underground in the mantle, the layer of hot rock between Earth’s surface and its core.
The huge size of the reservoir throws new light on the origin of Earth’s water. Some geologists think water arrived in comets as they struck the planet, but the new discovery supports an alternative idea that the oceans gradually oozed out of the interior of the early Earth.
“It’s good evidence the Earth’s water came from within,” says Steven Jacobsen of Northwestern University in Evanston, Illinois. The hidden water could also act as a buffer for the oceans on the surface, explaining why they have stayed the same size for millions of years.
Pinging the planet
Jacobsen’s team used 2000 seismometers to study the seismic waves generated by more than 500 earthquakes. These waves move throughout Earth’s interior, including the core, and can be detected at the surface. “They make the Earth ring like a bell for days afterwards,” says Jacobsen.
By measuring the speed of the waves at different depths, the team could figure out which types of rocks the waves were passing through. The water layer revealed itself because the waves slowed down, as it takes them longer to get through soggy rock than dry rock.
“We should be grateful for this deep reservoir”
Jacobsen worked out in advance what would happen to the waves if water-containing ringwoodite was present. He grew ringwoodite in his lab, and exposed samples of it to massive pressures and temperatures matching those at 700 kilometres down.
Sure enough, they found signs of wet ringwoodite in the transition zone 700 kilometres down, which divides the upper and lower regions of the mantle. At that depth, the pressures and temperatures are just right to squeeze the water out of the ringwoodite. “It’s rock with water along the boundaries between the grains, almost as if they’re sweating,” says Jacobsen.
Damp down there
Jacobsen’s finding supports a recent study by Graham Pearson of the University of Alberta in Edmonton, Canada. Pearson studied a diamond from the transition zone that had been carried to the surface in a volcano, and found that it contained water-bearing ringwoodite, the first strong evidence that there was lots of water in the transition zone (Nature, doi.org/s6h).
“Since our initial report of hydrous ringwoodite, we’ve found another ringwoodite crystal, also containing water, so the evidence is now very strong,” says Pearson.
So far, Jacobsen only has evidence that the watery rock sits beneath the US. He now wants to find out if it wraps around the entire planet.
“We should be grateful for this deep reservoir,” says Jacobsen. “If it wasn’t there, it would be on the surface of the Earth, and mountain tops would be the only land poking out.”
