Just stating the obvious conclusions.
If oxygen is the 3rd most abundant element in space, and space was here before the Earth...
Then how was the Earth here without oxygen?
Just stating the obvious...
And as I covered before: Scientists discovered the first life that requires zero oxygen over 2 years ago.
We only need oxygen as the "energy giver"... it reacts with carbohydrates in an exothermic reaction giving energy. There's only 20% oxygen in the air
we breathe and 100% oxygen is not really good for our little bodies.
But since oxygen is our electron acceptor we say we "breathe oxygen" when in reality we breathe more nitrogen (about 80% or something) but nitrogen
doesnt "give energy".
There are however organisms that have different electron acceptors like sulfate (hmmm SO4?) or nitrate (NO2) or even ferric iron. Thus they dont
"breathe" oxygen if their electron acceptor is not oxygen.
I'm saying this and I have no idea why we evolved using oxygen as our electron acceptor since its not stable as nitrogen for instance and has to be
constantly regenerated... flawed design? If we could get "energy" from nitrogen (its still reactive but not as much as oxygen) we'd breathe a more
stable and abundant source of energy that doesnt really need to be renewed by biological processes. Its like a blackmail for humans (well yes and for
animals but we're the big guys on the block and its my species so for me its more important lol there)... Like You want to keep living? Keep the
photosynthesis or else you're gone. This was a rather weird choice making our existence dependent and never fully grown out of the "blackmail bubble".
Its like a parent that says "you want to move? Ok, so I'll stop giving you money. You want money, stay here and behave" - of course on this particular
case you do have a choice, its harder but you have a choice - in life you do not. You are doomed to need other species to assure your own existence.
That makes us fairly fragile... and although oxygen is a very high energy chemical, our bodies could have adapted to require less energy to depend on
a more inert (but that still reacts) chemical that was stable and could secure our independence as a species... like nitrogen.
Anyway... saying oxygen is the third most abundant element is a weird paradox to our existence. One, how do they know its the third...? Well and why
dont we depend on the MOST abundant element in the universe (hydrogen?) and if it is the third most abundant element why do we have more nitrogen
(actually 4 times more) than oxygen in the air we breathe? We should either breathe the most abundant on the universe or at least the most abundant in
our "air"... and if the first most abundant element is hydrogen and the second is helium I think, the thid is oxygen and the others they say their
"RARE", why the hell we have 80% of it in our atmosphere? making it actually the most abundant element to breathe on earth which is where WE LIVE...?
Ok so Im an historian not a chemist but... try to help a fellow layman here
Wow... rambling... sorry guys.
