[...]nt the range of the estimates while time is measured in billions of years ago (Ga).
Stage 1 (3.85-2.45 Ga): Practically no O2 in the atmosphere. The oceans were also largely anoxic with the possible exception of O2 gases in the shallow oceans.
Stage 2 (2.45-1.85 Ga): O2 produced, and rose to values of 0.02 and 0.04 atm, but absorbed in oceans and seabed rock.
Stage 3 (1.85-0.85 Ga): O2 starts to gas out of the oceans, but is absorbed by land surfaces. There was no significant change in terms of oxygen level.
Stages 4 and 5 (0.85-present): O2 sinks filled and the gas accumulates.[1]

history of life is tight to hisory of oxygen --> fire
Aerobic metabolism is more efficient than anaerobic pathways
Abiogenesis: the natural process of life arising from non-living matter, how pre-life chemical reactions gave rise to life on Earth
•self-replicating molecules
•RNA world --> catalyze peptide ligation or amino acid polymerization --> protains, specialized biocatalysis --> RNA + iron ==> DNA : data storage
•synthesized from inorganic compounds
•catalysis in chemical systems =?=> molecules necessary for self-replication
•this is a protain writing
*water
Study of zircons has found that liquid water must have existed as long ago as 4.4 Ga, very soon after the formation of Earth [...] water with similar deuterium-to-hydrogen ratio was already available at the time of Earth's formation, as evidenced in ancient “eucrites” meteorites originating from the asteroid Vesta.

[with Guy Debord]
fire media theoretic
‘image’ detached into a stream, percieved as generality --> an inversion of life (“visible” negation of life - that has invented a visual form for itself)
(its social practices)
fire, not subordinate, as spectacle comes as means of unification, locus of illusion, generalized apparition --> seperation
(its general truth) fire untouched by evolution and form binding constrains, is a universal mater, the spectacle of burning flame manifests itself as a positivity out of reach and beyond. the case of fire is different than Deobord spectalcle who speaks: “Everything that appears is good; whatever is good will appear.”
therefore fire specatle is not image, rather social relationship between subjects that are mediated by it
thus the function and phenomenon of separation mediated by fire becomes part and parcel of the unity of the world, from now on
-a new form of the sacred emerged with the discovery of fire's image
-produced new worshipful subjection
the language of the fire as spectacle is composed of signs that talk to Moses, Zaratostra, and others
-in this writing i like to rewind theology and pause at the moment Moses meets Fire in mount sinai, go after some media theoretic specualtions, asking what are the conditions of this (inter)mediated encounter? and what are the consequences of talking to fire? (technicity and affectibilty)
(mount sinai : cradle of stone, rendered dead matter when ‘he’ comes out of stone-age)
•the Israelite's God, who appeared “by day as a cloud and by night as a fire” (Exodus 13:21)
[fire and brimstone, an idiomatic expression of signs of God's wrath in the Hebrew Bible (Old Testament) and the New Testament.] --> the fate of the unfaithful
(--> perceptible to the naked of the prohpet)
fire's mechanisms of contemplation
(in my preaching here i won't do what christians used to encourage repentence)
it is important not to put fire in abstract opposition to concret stone activity
mystic order ~?-> spectacular order
the spectalce of fire reciprocal alienation was part and parcel of human social life and its essence underpinning its relations to the real
diversities and contrasts in looking into the image of flame
what is already in society that fire (spectacle) gives expression? the beyond
(fire, we are) governed by its agenda
***monopolization of the realm of appearances*** (excluding other illusions, apparition, tellings, etc.)
-with fire a new brand of storytelling
***fire's spectacular aspect (accumulated to the point that) produces an image-object that is a seperate entity [accumulation --> generality/category --> new object], that of the mediated, from the fire itself, a second objecthood detached from its materiality, introduing transcendent immateriality --?--> metaphysics
-taking over life and existence
from vision to wisdom
categories of visulaity took human cognition hostage, gave rise to a metaphysical tradition/abundance imposing itself upon existence, regulating the perception of material life, philosophizing ‘reality’ to ‘beyond nature’ : *alienated thought* (due to the alienated power of fire) --- immaterial specatle of the afterlife, the world-beyond rendering life dead
abounding in metaphysical subtleties
-metaphysical abundance
...allegiance to the frozen
(Rumi's calling) “You must burn!” - this is very selfish
[to Siyavash?]
still today in sci-fi we are talking to a technoilogized light (as the messenger of beyond)
fire, transforms the world, not in terms of changing manifest matriality, rather the mind and thinking
fire in its temporal animation renders space fixated, giving the illusion that (visual) animation = life {~= spectacle}
the fire spectacle colonizing our participation with the beyond, colonizing the way our flux of senses make tentative contact with the other sides,
(what a stone suggests? the senses that never stop participating, never stop throwing themselves beyond the immediatly visible)
every phase of existence

[Scott Gilbert]
(all organic beings have been formed on two general laws, according to Darwin:)
(1) unity of type and (2) conditions of existence --> inorganic? fire?
natural selection --> adaptation --> conditions of existence
embryonic homologies --> unity of type
==> “descent with modification” (or decent modifications)
[(embryology =/=) ‘fire’ could transform matters, “change” their class, their type and its unity --> “parvaneh sho!” Rumi wants embryology undermined?]
construct phylogenies
(phylogeny : branching out evolutionarily)
small genetic changes was not sufficient to generate evolutionary novel structures such as teeth, feathers, cnidocysts or mullusk shells (Goldschmidt, 1940) (--> lizards had birdness in it --> potentiality [~-> mutation is not random])
(Waddington then launched into a) critique of the notion of “random mutation,” noting that there are developmental constraints placed on what changes are possible.

(Haraway on Burning Man:) Fire in the North American West has a complicated multispecies history; fire is an essential element for ongoing, as well as an agent of double death, te killing of ongoingness. The material semiotics of fire is our times are at stake.
[]three icons (suggestions by Haraway, three “-cene” tuned tor the touch of its critters):
1- ‘missing ice’ of the Capitalocene
2- ‘flame’ of the Anthropocene
3- ‘red clay pottery’ of the Cthulucene
(Conley >) Rosolato treats perspective in terms of the origins of sensuous affect:
infant's projective activity + infant closes its eyes to fend off menace, hence negotiating with the real in a space and time prior to the mirror stage

The artful sandwich of Rostam-rock-div provides a thinking mode of who-caries-who: whose being is dependent on whose existence. The earth that the Rostam is laying on, is sacred, on the hands of an ancient creature, who has a very delicate way of “wounding” very much different than Rostam’s quick hit-man [...]
