In 1650, an archbishop dated creation to around 4004 BC. Centuries later, Young Earth Creationism became a major American movement—and the debate continues.

Oxygen was a later addition to the Earth's ecosystem, relative to life (there were about 2 billion years in between).
So, what did they "breathe"?
Probably mostly iron and hydrogen, and it wasn't very efficient.

Earth, Sweet Earth ( Science For Everyone) by Ekaterina Radkevich
The book is based on the author’s impressions of her numerous expeditions in the many countries. It is a fascinating narrative rather than a mere record of facts irrespective of how scientifically valid they can be. The book is bound to be appreciated as a piece of absorbing reading by anyone who cares to increase the scope of his or her competence about our sweet home of a planet that must be saved from destruction at all costs.
Ekaterina Radkevich, Corresponding Member of the USSR Academy of Sciences, is one of the most distinguished geologists whose works are well known in her own country and in many other parts of the world. The overwhelming success of her publications is chiefly due to her indefatigable practical activity in the USSR and elsewhere and her unflagging interest in theoretical research which she has been conducting for quite some time at the Institute of Geological Studies in the Far East (Viadivostok).
Note: This book was the last remaining volume in the Science for Everyone Series! This completes volume the SFE series in English.
Many, many thanks to Hassaan Ali who purchased and posted this book to us to complete this series. Much appreciated help!

"It seems that everything was a target for this vicious, mass-murdering tree."
Witness the stunning beauty of nature’s timeline! 🌍 In this tranquil scene, the exposed rocky layers tell a story of millions of years of geological evolution, shaping the landscape we see today. Each stratum holds secrets of the Earth’s ancient past, beautifully juxtaposed against the still waters and lush forest.

An interesting study of the hypothesis that the Sturtian "Snowball Earth" event from around 720-660 Mya was caused by a Large Igneous Province eruption, through a very comprehensive exploration of model parameter space.

The basic idea: the Franklin LIP, now in northern Canada, erupted at low latitudes: this led to enhanced silicate weathering that removed of CO2 from the atmosphere fast enough for the (positive) ice-albedo feedback to overcome the (negative) silicate weathering feedback.
The question asked here: could this mechanism work, and if it did, why didn't more recent LIP eruptions at tropical latitudes have similar effects?
The answer: yes, under certain conditions that are more easily met in the Neoproterozoic than the Phanerozoic:
- low starting temperatures
- rapid weathering & erosion, possibly due to (lack of) plant cover
- a weaker silicate weathering feedback

Modelling suggests that Earth's first crust, which fractionated from a magma ocean, would have had a similar trace element composition to modern continental crust: in other words, this signature is not a reliable marker of subduction and plate tectonics on the young Earth.
The protoplanetary material that coalesced to form the Earth had lots of intrinsic hydrogen bound with sulphur - probably enough to support hypothesis that Earth's water came from outgassing of mantle rather than being supplied by comets and asteroids.

Complex life on Earth may be much older than previously thought. Fossils and geological evidence indicate that multicellular organisms might have existed over a billion years ago, pushing back the timeline of life's evolution. This discovery could reshape our understanding of how life developed on our planet, offering new insights into Earth's ancient history and the conditions that made life possible.

After the Great Oxygenation Event around 2.4 billion years ago, lots of now-unstable sulphide minerals like pyrite reacted with the oxygen now appearing in the atmosphere, making stream and river water extremely acidic - and apparently screwing up a proxy that has been used to argue that Proterozoic oxygen levels couldn't have been very high.

One of the humbling takewaways from this book is how insignificant we human beings are - how brief our time on earth has been
compared to all of nature.
‘This is not our world with trees in it. It's a world of trees, where humans have just arrived.‘
To get a sense of how brief our time on earth is in light of all of earth's history - check out this fascinating video:
https://www.youtube.com/watch?v=S7TUe5w6RHo
Serendipity! How a 2.4 billion year-old rock “picked up by chance” turned out to contain surprisingly complex microfossils: "the first direct fossil evidence linking the changing environment during the Great Oxidation Event with an increase in the complexity of life."
