OpenAI on the subject of climate optimums,,,

User:

When would have been the most recent climate optimum prior to the holocene?

ChatGPT:

The most recent climate optimum prior to the Holocene was the Eemian interglacial, also known as Marine Isotope Stage 5e (MIS 5e). The Eemian occurred approximately 130,000 to 115,000 years ago. It was a period of relatively warmer temperatures compared to the surrounding glacial periods, and it is considered the last interglacial period before the current Holocene epoch.

During the Eemian, global temperatures were somewhat higher than those of the present interglacial (Holocene), and sea levels were higher as well. This warm period is named after the Eem River in the Netherlands, where sedimentary deposits from this time were first studied. The Eemian interglacial was followed by a glacial period, and the Earth experienced subsequent glacial-interglacial cycles leading up to the present day.

=====================================

Numbers at least ballpark for the same...

The Ganymede Hypothesis posits a transfer of humans from Ganymede to the middle of the Pacific ocean and thence to Australia some tens of thousands of years ago and there is no real way to put an exact date on that. Likewise the roughly 120000 year figures mentioned in the article about native Australians and in OpenAI's description of the Eemian optimum could easily be off by a factor of two, but you may be starting to get the idea.

Ryan Darger's image now serving as the group image for the Ganymede Hypothesis group on FaceBook shows the bright. sun/Jupiter facing side of Ganymede:

But Ganymede had a dark (or back) side as well and logic says that those first humans to transfer to Earth would have transferred from that back side and not the bright side.

Two questions: what was making that back side bright enough for humans to want to be there near the time of the transfer, and what was making Earth warm enough that those humans who splashed down in the Pacific ocean didn't just freeze to death or die of exposure?

=========================

Here is the working hypothesis, such as it is:

Purple and gold were "royal" colors because those were the primary colors of the sky in the two ages of the world prior to ours. I would have thought that the purple age was the primordial condition of the planet, unchanged , unchanged prior to the Holocene, but that may not be the case.

The early Holocene seems to correspond to the Greco-Romanclassical age during which Saturn had ceased being a brown/purple star and was providing golden light to the world. That was ended by the capture of the Saturnian system and the flood.

The dates they give for these things are hugely questionable but the Eemian climate optimum could easily be construed to have coincided with that first near approach of the Saturnian system to the sun/Jupiter system and the transfer of humans to Earth.

If the Eemian had also produced a golden age, possibly also lasting several thousand years, that would seem to answer both of our questions. People on the backside of Ganymede thus might have been seeing something like this for a few centuries prior to the transfer event

Again, OpenAI describes the Eemian as the most recent climate optimum prior to the Holocene, and as warmer than the Holocene. The hypothesis here is that those first humans to transfer from Ganymede splashed down in the Pacific ocean in the middle of a deep prehistoric climate optimum and golden age, and were then shepherded to the nearest point of dry land, i.e. Australia or some place in the neighborhood of Australia, by whales and other aquatic mammals. That qould be in keeping with symbiotic relationships amongst aquatic mammals including humans at the time.
