And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. Genesis 1:6
"Kasting was commenting on a letter to Nature in the same issue, and placing the research within historical context. He explained that
However, as the article points out, there are two major problems with the timing of this ‘GOE’.
First, if oxygen producing bacteria supposedly evolved some 2.7 Ga ago, why then did it take at least 300 Ma, and possibly up to 700 Ma, before oxygen comprised a significant part of the
atmosphere? The significance of this time interval is that it is potentially longer than the entire timeframe of the fossil record (the Phanerozoic), and is exceedingly slow even by evolutionary standards.
The second problem is that carbonate rocks formed before and after the supposed ‘GOE’ show the same carbon isotopic signatures. The burial of organic carbon from photosynthesizing organisms should cause the ratio of 13C to 12C in carbonates to rise. This leads to a huge contradiction as explained in the article:
It is the naturalistic evolutionary framework that is the problem. Within this framework a reducing atmosphere is needed initially if the first cell is to have any possibility of arising by chance.
But it must then change into an oxidizing atmosphere to permit the evolution of aerobic bacteria and multi-cellular life.
These problems disappear when the problem is approached from a biblical framework. There never was a great oxidation event because oxygen, at concentrations necessary for life to flourish, was present in the atmosphere during Creation week at the beginning.
The geological evidence, including sulfur minerals and carbonate rocks, is explained by deposition during the early part of the global Flood."

‘The [scientific] consensus for more than 30 years has been that atmospheric oxygen first reached appreciable levels around 2 billion to 2.4 billion years ago, an occasion referred to as the great oxidation event (GOE).’Naturally, the issue of the timing and origin of the oxygenation of the atmosphere is significant because it is central to the origin of life and evolution.
