Early Earth Was Almost Entirely Underwater, With Just A Few Islands
universe today ^ | 05/13/2017 | Evan Gough

4.4 billion years ago, the Earth was in what is called the ‘Hadean Eon’. This time period is poorly understood, because there is no rock record dating from that time. This is where the zircon mineral grains come in.

...

In a sense, these zircon grains are the missing pages.

Zircon’s chemical name is zirconium silicate, and it’s found almost everywhere in the Earth’s crust. This study focuses on what’s called detrital zircon, which is formed in igneous rocks, but then survives over time until deposited in sedimentary rocks. Zircon grains are typically very small, about 0.1 to 0.3 mm in size.

Zircon commonly contains traces of thorium and uranium, which means they can be easily dated by modern dating methods. Zircon can survive a lot of geologic processes like metamorphism, which explains their usefulness in studying the early Earth. They’re not easily destroyed, and they have a story to tell us.

The zircon grains were crystallized in magma about 500 million years after the Earth formed. As a result, they offer rare insights into conditions on Earth at the time. The zircon grains in question are referred to as detritus, because they formed in magma but were deposited in the geologically-important sandstone at Jack Hills, Australia. The detritus grains were compared to a second type of zircon grain which were formed directly in the sedimentary formations.

By distinguishing between the two types, researchers gain a new geochemical tool to understand early Earth.

So it’s almost like... in the beginning... the earth was formless and desolate. The raging ocean that covered everything was engulfed in total darkness.

I think that might be in a book I read somewhere.

So many silly memes...
Earth should sue the Big Bang for predatory mortgage lending. But of course there’ll a “the Big Bang too big to fail’ call for government intervention.

Early Earth was under water...after the first flood. God destroyed all life on earth early on...Noah’s Flood was the second flood. After that, God put the rainbow in the sky as assurance that he would not destroy the earth by flood another time.

Read Genesis 1...

The fact that there is evidence of a previous creation us enough. The pre-humans, the Dinosaurs are evidence.

Does this mean that there was a fall of pre-man and that sin entered the world prior to Adam?

Genesis 1:2 The earth ‘became’ void and without form... This is describing the casting down/overthrow of Lucifer ... Isaiah 14:12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!

And yes, Genesis 1:2 says And the earth was (should be ‘became’) without form, and void; and darkness was upon the face of the deep.

(deep what?)

And the Spirit of God moved upon the face of the waters.

Hey scientists -- look over here. Those "missing pages" are right in Genesis, chapter 1:

1 In the beginning God created the heaven and the earth.

2 And the earth was without form, and void; and darkness was upon the face of the deep.

...

9 And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so.

10 And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good.

Amazing how “science” keeps rediscovering the biblical truths.

There was a time when you could walk from France to England, from China to Japan, from Asia to North America.There was a time when the earth was possibly an almost a total ice ball. Man’s influence on climate is nil and then some.

A fun book to read is Bill Bryson’s “A Short History of Nearly Everything.” Lot of geological facts. Not actually extremely factual but a good read.

The most interesting speculation. The Siberian air runs south and bounces off the Himalayas. Gives us our jet stream which is now (Omg!) our Polar Vortex.

The only place in the entire K.J.V. that the name “Lucifer” is mentioned.

True... The ‘light’ left him when he decided he would be ‘god’. In Ezekiel 14 his title was ‘king of Tyrus’... He has many titles/names.. It is Written a third of the children followed him at his rebellion... He is the only named entity that has already been judged to eternal death... On any given day it seems that third are walking this earth today.

This means that we are running out of water!!
We must stop the land from rising!
The only way is to raise taxes!
Wait! There is another way! Stop drinking water!
The more you drink the faster the land rises.

It gets even more interesting when you consider, “Where did the rest of the water go?” A question for which there may be an answer.

(2014) Vast Underwater Ocean Trapped Beneath Earth’s Crust

http://www.natureworldnews.com/articles/7560/20140613/vast-underwater-ocean-trapped-beneath-earths-crust.htm

https://en.wikipedia.org/wiki/Ringwoodite

“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 in the mantle transition zone from 410 to 660 km deep.”

Then the next two questions are the real zinger.

1) How did all that water get from the surface to deep underground? And,

2) Could a significant amount of that water come up again?

What comes to mind is straightforward.

Earth was formed about 4.54 billion years ago. About 4.51 billion years ago, according to the giant impact hypothesis, a Mars-sized planet called Theia collided with the Earth, creating the Moon.

A relatively short time thereafter, at 4.4 billion years, the Earth was mostly covered in water, with very high atmospheric surface pressure of around 27 atmospheres, caused by a heavy CO2 atmosphere. Most major geological changes came about because of hot magma plumes, and only when they died down did plate tectonics begin, at around 3.2 billion years.

So what pushed all that water between 250 and 450 miles deep?
