I rarely discuss scientific principles or results because most people have no idea how things work and I'm not all that much better. But the behavior of gas is a simple enough concept I'll try anyway. CO2 is often released deep in the earth as part of the carbon cycle. Frequently this gas is released at great depth in the presence of water. The water will typically be cool (~56 f) and under great pressure due to its depth (the weight of the earth above it). Generally the cooler a liquid is and the higher the pressure it is the more gas it will absorb and this is certainly true of CO2 and water.
This combination is highly acidic and also called carbonic acid. If the water than approached the surface some CO2 will be released and can travel with it. If this carbonic acid and CO2 get near enough the surface the water near the top can lose its carbonation explosively and well up out of the earth like a shaken soda. This causes a cascade event as it lightens the pressure on the water below. This process is known to us as a CO2 geyser but ancient people didn't think like we do. They called the process "3gb" and the event "the inundation that tosses" or scientifically "duat". It happened on the horizon and shot to heaven. The CO2 was "I3.t-wt.t" scientifically or "efflux" colloquially. Creation began in nun when the lunar element water combined with the solar element CO2 and it sprayed through the eye of horus at the "Mouth of Caves" where the gods built the instruments of ascension.
Whenever these geysers weren't erupting there was typically small or large amounts of CO2 wafting up from openings in the earth. They sealed these with mixtures of clay and straw but the pressure was great enough that much still seeped up and when a temperature inversion happened at night as they are prone to do and the wind slowed because solar heating stopped this CO2 could build up at ground level because CO2 is heavier than air. This accumulation was very dangerous leading to the construction of the builders village far from the construction site and located behind a massive wall.
No doubt over the centuries many men and even whole teams were found dead in the morning which is the origin of man's fear of "snakes". These fluid flows were called "snakes" or "serpents" and they were always dangerous and sometimes fatal. Indeed, they are probably still dangerous at Giza since there is still water bubbling up there and there is a dust sitting on the water in the Osiris Shaft. I believe this dust is insect components broken down without the presence of oxygen.
All the data to solve this is easily found and the results of ancient science await right behind the thermal anomaly.
