[P]reserved crystallized salts in Russia that are dated to this period..were extracted from a 1.9 km-deep (1.2 mi) hole in Karelia in northwest Russia.

I knew it was the Russians!

Waiting for someone to post the Total Recall finale segment.

It was the great oxygen farting giant turtle, A’tuin
who created an oxygen rich world !

What I find amazing is photosynthesis only evolved one time. What if it had never evolved at all?

Genesis 1:1 is much easier to believe—maybe because it’s the truth from the Author of truth.

There is only one First Cause.

Big Bang ... caused by God.

Later.

Great Oxidation Event ... caused by God.

Don't Panic. It took the builders a little while to get the oxygen contract in motion.

Here’s my theory: The Earth was a big snowball. Then asteroids missed the moon and clobbered the Earth. The resulting heat melted the ice and disassociated some of the H2O into H and O. Over time the H seeped into space leaving a lot of O2. At least, that’s what my model is telling me.

[ImJustAnotherOkie]

Just like the old Total Recall movie?

[robel]

Odds of it happening like they hypothesize? Incalculable.

[snip] ...our planet's primordial atmosphere was toxic to life as we know it, consisting of carbon dioxide, nitrogen and other gases. However, by the Paleoproterozoic Era (2.5–1.6 billion years ago), a dramatic change occurred... known as the Great Oxidation Event (GOE)... the introduction of oxygen to our atmosphere was "more like a fire hose" than a trickle... the oceans and the atmosphere... contained a surprisingly large amount of sulfate, which is the result of seawater reacting with oxygen.... the ancient seawater from which those minerals precipitated had high sulfate concentrations reaching at least 30 percent of present-day oceanic sulfate as our estimations indicate. This is much higher than previously thought and will require considerable rethinking of the magnitude of oxygenation of Earth's 2-billion year old atmosphere-ocean system." [/snip]

Thanks BenLurkin.

• The Origin of Nitrate Deposits
• The Transmutation of Oxygen into Sulphur
• The Origin of the Oceans

  [snip] Paleontological research makes it rather apparent that marine animals in some early age were more closely related to fresh-water fauna; in other words, the salinity of the oceans increased markedly at some age in the past. [/snip]

The knots atheists tie themselves into, are simply amazing.
