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.
Zircons chemical name is zirconium silicate, and its found almost everywhere in the Earths crust. This study focuses on whats 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. Theyre 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.

They got the facts right, they are just a little bit off on the timing.
Apollo 8 wasn’t it? Christmas Day during their fly-by; semi orbit of the moon?
“Water World” was actually a documentary about the same subject his article is concerned with. Just beat the article by about 10-15 years.
Anyway, Jeanny Tripplehorn (sp?) was hot.
Re “500 million years old magma”. Hell’s bells. I’ve got bagels older than that, and just as hard.
Yeah, and the only land he found was where I live now, so good luck, y'all.
So... are they saying the earth was flooded?
Interesting stuff! Amazing how much the earth itself and it’s climate has changed over a few million years... But then somehow everything that has happened to our climate over the past 50 years is caused by man.
I would really like to know who determined we just caused ourselves to move past the optimal “world” climate anyway...
Pretty cool thread.
Hear ye hear ye, the earth was once COMPLETELY under water.
A story several years back about the findings from zircon crystals also revealed that the early Earth was a nice place and not a hellhole. Blue sky, good weather, oxygen in the atmosphere, We could have lived there.
If only we could ask the aliens likely watching us and determining that our planet is like their planet from only 10.5 light years away.
Perhaps some researchers would be more sure of what makes earth tick if only they had a more distant perspective.
Seems great distance makes for more positive postulating.

How many sons and nephews did "Lucifer" have, exactly?

Which wouldn’t be that big a deal - if fallible and uninspired religious tyrants weren’t trying to assume dominion over the faith of others, declaring that anyone who recognizes the self-evident fact the Universe is much older than 6000 years... can’t possibly be part of THEIR body of Christ.
..and in the process, castrating multiple generations of their ability to apply Logic, Reason, and Science toward exposing other silly notions, such as the LGBTQXYZ culture’s “gender fluid” farce, for the delusional FRAUDS they are.
You seem a bit upset. To my mind the answer is simple... there have been numerous creations... study the Julian Calendar. I would link my web page, but I doesn’t know how on this Kindle... sigh
"...who, being themselves but fallible and uninspired men, have assumed dominion over the faith of others, setting up their own opinions and modes of thinking as the only true and infallible, and as such endeavoring to impose them on others, hath established and maintained false religions over the greatest part of the world, and through all time;...that it is time enough for the rightful purposes of civil government, for its officers to interfere when principles break out into overt acts against peace and good order; and finally, that truth is great and will prevail if left to herself, that she is the proper and sufficient antagonist to error, and has nothing to fear from the conflict, unless by human interposition disarmed of her natural weapons, free argument and debate, errors ceasing to be dangerous when it is permitted freely to contradict them.

Good heavens... What did I say?
Lucifer had dominion over the earth. When he and his angels were cast out of heaven, my speculation is that the earth was flooded and the waters froze, wiping out everything in that earlier creation.
Interesting theory. Not saying I necessarily agree with it or not, and it doesn’t have bearing on one’s salvation anyway. But it is a new one to me. Might have to file that away for future reference and rumination.
Just illustrating how I’m no more or less “upset” than Thomas Jefferson - or the others who decided they’d had enough of the temporal Dominionist’s antics.
