I've read quite a lot about geology, deshy poo. And have fossils in my back yard to avoid stepping on when going out there barefoot.

Thank the gods that I'm pretty regular then.
Hopefully you don't get the 'rona and your immune system only knows how to combat the 1st 'rona and not the mutation that you get.
I've had the vax x2 and the booster x1, and the virus x2 as well. Then I had a hideous non-COVID upper respiratory infection thanks to my g-kids. That was worse than the COVID which was a day or so of slight fever and sore throat and a few more days of coughing and being tired. I'm quite confident that the COVID would have been a lot worse w/o the vaccine.
3.5 billion year old fossils of prokaryote bacteria from Precambrian rocks in Australia and South Africa.
Because there were no photosynthetic organisms on earth 3.5 billion years ago. Free oxygen (O[SUB]2[/SUB]) is highly reactive and would never even exist in our atmosphere in appreciable amounts without photosynthetic plants and bacteria. The oxidation state of iron-bearing rocks from the precambrian rocks tells us there was a shift in atmospheric composition from an oxygen-depleted atmosphere, to an oxygen-rich atmosphere --> This happened because of the evolution and widespread distribution of photosynthetic cyanobacteria (around 2.5 billion years ago, I think); cyanobacteria respirate free oxygen back into the atmosphere as a by product of photosynthesis.
I am curious as to which branch of actual science has published a paper on ballot harvesting which you claim is science. Can you point me to the scientific journal?
Yale University Department of Earth Sciences: "Geochemistry is the branch of Earth Science that applies chemical principles to deepen an understanding of the Earth system."

Radiometric isotopes
National Academy of Sciences paper --> "Strong isotopic evidence for a weakly oxygenated ocean–atmosphere system during the Proterozoic"
Summary: "We use the isotopic record of iron oxides deposited in ancient shallow marine environments to show that oxygen remained at extremely low levels in the ocean–atmosphere system for most of Earth’s history"

There are various tricks to see where either the environment of early times, or more often the effects of the environment has been trapped in place. Obviously, I am not an expert on this all, nor are you. If you think you can make major breakthroughs in the field of paleo biology, you should become an expert, and try.

There are detailed studies of this process, like this one:

My favorite are cosmology, paleoanthropology, genetics, Earth & planetary sciences.
I really just can't get into botany or entomology, but maybe someday I should give them a chance.
Political papers published by partisan groups are now science? Since when?
Do you even know what a scientific journal is or the process of peer review?

They are when it's political science. That's a quack liberal arts field--you know, like Womyn's Studies, or Critical Whatever Theory-- and the appropriate one for nonsense on politics...
Origin of life theory involving RNA–protein hybrid gets new support
Structure that links amino acids suggests that early organisms could have been based on an RNA–protein mix.
Chemists say they have solved a crucial problem in a theory of life’s beginnings, by demonstrating that RNA molecules can link short chains of amino acids together.
The findings, published on 11 May in Nature1, support a variation on the ‘RNA world’ hypothesis, which proposes that before the evolution of DNA and the proteins it encodes, the first organisms were based on strands of RNA, a molecule that can both store genetic information — as sequences of the nucleosides A, C, G and U — and act as a catalyst for chemical reactions.
The discovery “opens up vast and fundamentally new avenues of pursuit for early chemical evolution”, says Bill Martin, who studies molecular evolution at Heinrich Heine University Düsseldorf in Germany.

Holly Rollers will holler that abiogenesis isn't science because it's not testable.
Abiogenesis is the hypothesis that prebiotic chemical processes could lead to cellular life.
Processes, especially as complex as abiogenesis, would require many preliminary and intermediate chemical steps between inert prebiotic chemicals, and the cellular structure of a self replicating prokaryotic cell.
Many of those intermediate chemical steps have been tested, including the spontaneous generation of amino acids, peptides, and precursors to RNA under laboratory conditions.
Even if a prokaryotic cell is never generated from probiotic conditions, that doesn't mean there was never any science involved. It means we would have to totally rethink the hypothesis that prebiotic chemical processes were responsible for cellular structure. Failed tests are still perfectly valid scientific inquiries, and are an expected part of the scientific method.

How do you know what 'early' conditions of Earth were like? How do you know life originated on Earth through a series of random unspecified events?

Fossils have no age. Free oxygen is not highly reactive. It exists in our atmosphere today. Why do you figure that photosynthesis was not on Earth? What is your first cell going to eat? It is not capable of photosynthesis. That requires complex structures that you say don't exist yet.

Science is not a journal nor an election.
