Almost on all continents of the Earth there are underground cities and there are hypotheses for what they were built. But as a rule, they all boil down to one opinion, for the salvation of mankind. But opinions differ from what mankind was saving from, here and from nuclear war, but no traces of the use of nuclear weapons were found near them. And from the flood, there are no traces either. And to hide the population from the conquerors. And even the population was hiding from evil aliens. And what if the reason lies in the following. As you know, according to the calculations of astronomers, between the orbit of Mars and Jupiter there must be another planet, its most famous name Phaethon. But now there is an asteroid belt, i.e. there is a high probability that the planet was, but for some reason exploded. Moreover, the planet was in the belt of life, which means that there is also a high probability thatthat the conditions on it were similar to those on Earth. But in this case, the planet should have had reserves of hydrocarbons: oil, gas, bitumen and gas hydrates or clathrates. During the explosion of Phaeton, large fragments mainly continued their way along the orbit of the planet, but some of the debris, especially small ones, including hydrocarbon formations, scattered to the sides and, under the influence of the Sun's gravity, formed new elongated orbits that intersect with the orbits of the planets. And if such clouds of hydrocarbon formations intersected with our planet, then a fiery bombardment of the Earth was obtained. The safest hiding place was underground. There may be an explanation why the ancients were so afraid of comets. Clathrates are composed of gas and water, and bitumen is also found at the bottom of the oceans,so these hydrocarbonaceous formations in space were mixed with water that was thrown out with them. When approaching the Sun, a tail with bizarre formations appeared. But at the same time, it was a signal to the population to go underground. Gradually, the number of such comets decreased due to their fallout on the planets of the solar system. But it cannot be said that they have disappeared completely. This can explain the destruction of Sadom and Gomora, the fire in Moscow in 1912 and the fire in Chicago in 1871. But perhaps if you delve into history, you will find more than one hard-to-explain fire that destroyed the whole city.

The melting point of granite is 1216 - 1260 degrees C. An ordinary fire cannot produce such a temperature, and some attribute this to the use of nuclear or high-temperature weapons in antiquity. But for some reason this option is not considered. Pieces of oil at extremely low temperatures turn into bitumen. When such pieces enter the dense layers of the atmosphere, they heat up and ignite, while at high speed they are blown by an air stream, i.e. combustion is supercharged. I wonder what combustion temperature the bitumen will show when burning with pressurization, I think far beyond 1000 degrees Celsius. And such a mass as napalm, adhering to the walls of buildings, could cause the stone to melt.
