There are I believe 6 carbonated lakes in the world and they are all in Africa.
"In the Monoun disaster, 37 people died after walking into a visible cloud around the lake."
I can't imagine ancient people walking down into a cloud. At least not in Egypt.
The largest is Lake Kivu in Congo/ Rwanda and is home to 2,000,000 people. It is too large to siphon off all the CO2 but they do remove some as well as lots of methane used for fuel. People who live here know about CO2 because it kills several children a year since they are too short to tiptoe and hurry away. The lake itself is dangerous and there's no way to know when it becomes unstable so evacuations can begin. Africa is also home to CO2 vents and some cold water geysers. The travertine mines up and down the Nile River are likely the product of carbonic acid deposition. There are warm springs only a few miles from Giza and this area sits on a transform plate boundary that is expected to begin spreading imminently. Earthquakes while not common can be severe. The Nile in this area was once a canyon 1.6 miles deep which I believe is significantly deeper than the grand Canyon. There are caves to great depth and two aquifers flow under here where the crust is a mere 22 miles thick.
About 3% of people (including myself) can smell CO2. I suppose I'm descended from people who survived a localized bottleneck from CO2.
Egyptologists don't know anything about this stuff so how are they going to see the nature of
"I3.t-wt.t"? They likely don't know much about CO2 either. They don't even know that
"I3.t-wt.t" is osiris sweat despite dozens of clues in the writing. (and my continually pointing it out)
So here we are with everyone knowing everything and most of all they know I'm wrong about everything.
Homo omnisciencis. People dismiss everyone who doesn't agree and they dismiss the stinky footed bumpkins who wrote the PT. Me? I know for a fact (axiomatically) that everyone makes sense but here I am with the ancients and we don't make any sense at all.
