I take exception to you presenting your story as if it was physical fact, when actually what we know of history going back to dinosaurs is not a lot.
This is you trying to build a cult following rather than genuinely trying to inform and help people, it seems to me. There is almost no way to verify many of the things you presented here as facts, but plenty of ways we can work out at least some of them can't be true.
At 260 degrees, water is no longer water, it would be instantly vaporised at that temperature in the open atmosphere.
The energy of a lot of those molecules of water vapor would exceed the force of gravity at the outer reaches of the much expanded radius of the atmosphere, swollen as it would be at that heat. In other words there would be a constant loss of water into space at that temperature on Earth. The water would literally be boiled off of the planet.
But look, we still have a lot of water.
So I doubt very much a temperature of 260 degrees or anything even remotely close ever existed on Earth, at least not since there has been life. Where did all the birds go, when all this was going on, were they bunkered, maybe together with a new water supply for Earth?
Sorry but we will never understand actual reality, like why it is so important to mathematically sign energy in and out of Earth, as long as you create stories like this, which folk actually believe, therefore resigning themselves to a planet past the best we can do for it or get from it.
We have a debt to Earth right now, it's an energy debt, ran up over thousands of years of taking energy from it.
We need to mathematically sign energy in and out of Earth to understand that, and to work out how to repay it, because the energy put to use on Earth is creation, whereas energy taken from Earth is destruction
All of this is easily verifiable by just drawing some diagrams and doing the sums.
Animals can't do that but humans can.
If they/we don't, then we sailed all the way into ending the planet, by exhausting all survivable energy on it, without even knowing it.
Anything born, is born by removing it's dependency from limited energy supplied by mother host for energy, to becoming dependent instead on the relatively unlimited energy of the environment.
Every plant does this when it first forms leaves then grows to thousands of times the size it was as a leafless infant, paying back it's energy debt to Earth thousands of times over.
The plant before it formed leaves was not a form of photosynthetic life, it only becomes that after it starts to deliver energy product to Earth.
After that, there is a flow of energy product through the plant to Earth, from the sun, via the nutrients in the plant.
The closest thing we have to nutrients is money.
Therefore money is what we have to use to transport the energy product received from the sun, to all people.
The only way this can be done is by issuing the money to all people, with nothing asked in return, because the sun asked nothing in return for the energy it delivered. We have to create money according to the energy received and issue it to all people, otherwise money will continue to devalue because it is not representing the energy received for free which is ramping up, whilst the enetgy dug from the planet has to ramp down.
Issue of that money will catapult us into rapidly scaling the rest of the way to solar by providing massive incentive and rewards for doing so.
Not knowing about that, would be the real existential wrong choice Indi, the real physical reason we didn't manage to be born as an "Intelligent" species.
