Granpa, question for you..
What is that you are trying to accomplish with your posts?
They are clearly copy pastes from some site. pretty colored, I see that.
But what is that you are saying? The point?
YOU. Not them.
I don't know what the point is, exactly, but that chart has a number of flaws.
For instance, there's no such thing as "nonbiogenic oxygen."
Oxygen in an atmosphere can only be produced as a waste product from breathing organisms. Christian apologists, though, love making up things like "nonbiogenic oxygen" to explain how oxygen can appear on earth before life did -- and things like that.
Another flaw is how oceans appeared on earth before the sun ignited -- which is impossible. The sun would have to be hot enough to melt the water-ice in the solar system for there to be any hope of an ocean on earth. A protosun -- which is essentially a brown dwarf at that point, a star that hasn't achieved nuclear fission yet, wouldn't be able to do that from 93 million miles away.

That is not exactly correct, Shirina. SETI Institute researcher Friedemann Freund has a completely non-biological hypothesis about the rise of oxygen, which has some experimental support from laboratory work that he’s done. The hypothesis is that, when rocks solidify from magma, they incorporate small amounts of water. Cooling and subsequent reactions leads to the production of peroxy links (consisting of oxygen and silicon atoms) and molecular hydrogen in the rocks.
Then, when the igneous rock is subsequently weathered, the peroxy links produce hydrogen peroxide, which decomposes into water and oxygen. So, if this is right, simply weathering igneous rocks is going to be a source of free oxygen into the atmosphere. And if you look at some of the quantities of oxygen that Friedemann is able to release from rocks in well-controlled situations in his initial experiments, it might be that this was a substantial and significant source of oxygen on early Earth. https://www.universetoday.com/9403/t...ygen-on-earth/
Smelting of iron oxide would also work. While the production of nonbiogenic oxygen would explain what happened to Earth's early hydrogen atmosphere it would not explain how objects like Ceres ended up with so much water. So right now I'm a bit conflicted and undecided.
Guess, there is none. At least, they are pretty.
Like my wife says - anything better than drugs and alcohol.
