Abiogenesis speculation
All that I am saying is if information and ideas are being covered that are mostly speculation why discriminate?
My "bolding".
It may well be hazy and highly speculative, but it is the only scientific route to pursue. And science is neither saying or denying that God was involved in abiogenesis. Personally, I say "Who cares how life on Earth originated?"
That is why everyone should learn both sides of a discussion with an open mind.
You are proposing some sort of Godly ID as an alternative? Isn't that equally, if not probably even more speculative? What are the details of the God/ID hypothesis of the origin of life? I say there are none, therefore there is no ID side of the discussion.

The origins of free Oxygen
That is why many models state that earths early atmosphere had much less oxygen in it, but there is no other evidence to suggest what amount of oxygen was in the air 4 billion years ago.
The origins of preCambrian Iron formations are believed to because of the origin of free oxygen in the atmosphere. Iron's reaction with the Oxygen caused it to precipitate out of solution.
The Wikipedia article: Banded iron formation
quote:
Banded iron formations (also known as banded ironstone formations or BIFs) are distinctive units of sedimentary rock that are almost always of Precambrian age. A typical BIF consists of repeated, thin layers of iron oxides, either magnetite (Fe3O4) or hematite (Fe2O3), alternating with bands of iron-poor shale and chert. Some of the oldest known rock formations, formed over 3,700 million years ago, include banded iron layers.
and
quote:
The formations are abundant around the time of the great oxygenation event,[2] 2,400 million years ago (mya or Ma), and become less common after 1,800 mya.
and
quote:
The conventional concept is that the banded iron layers were formed in sea water as the result of oxygen released by photosynthetic cyanobacteria (bluegreen algae), combining with dissolved iron in Earth's oceans to form insoluble iron oxides, which precipitated out, forming a thin layer on the substrate, which may have been anoxic mud (forming shale and chert). Each band is similar to a varve, to the extent that the banding is assumed to result from cyclic variations in available oxygen.
Caption for above at cited article: "2.1 billion year old banded iron formation"
I believe the 2.1 bya event is by far the most significant Iron formation event. That is the age of the great Iron formations in northern Minnesota, Wisconsin, and Michigan. I believe there is also 2.1 bya Iron formation in Wyoming.
There is other evidence such as tidal deposit sands and silts, and stromalites that indicate this Iron formation formed in shoreline environments.
