\section{Spreading of Humans} About $-100$ kiloyears ago, the plans dominate at the Earth. They consume the most of the carbon dioxide from the atmosphere. The carbon happens to be burried in the earth in form of coal and oil, at deepness from meters to kilometers belor the surface. Without carbon dioxyde, the atmosphere becomes transparent for the indrared light. This does not affect much the warming of teh Earth at daytime, but boosts the cooling of the surface at night, the surface of the most of the ground, escept tropical area, covers with ice. This reduce a litle bit consumption of the carbon dioxyde, but the ice reflects the solar light, and during centuries, the classiers consume a lot of water from the oceans, accumulating it with thick layer of ice. At year approximately $-50000$, something happens with the Earth. Either the moon drops away from fastly rotating planet, or, contrary, some bifr rock hits the planet. This causes vaporation of the ice in vicinity and burning of the layers of the coal amd oil, emittion into the space huge amount of dust and ache; it covers gletchers, coosting their melting. The strong rains cause the floading. Many animals and humans die. In subtropical zones, the glethers are melt, and the ice release the neq and new lands. They are covered with grass, bushes and trees. The wild humans provoke the wild fire, in order to protext themselve agaist dangerous predators, and also to burn some animals for food. Such a barbarian methif of hunting gorces Humans to move, looking for the places, where the forrest is not yet burned out. That cause migration of Humans, their spreadig over the planet. In uear -40000 – 15000, wild Humans populate not only Eurasia with Africa, but also America, generating varietie of the Human civilizations. The Human tribes interact each other. This interaction has several aspects: 1. Wars. Stronger tribes kill and eat the weakest. 2. Exchange with goods and technology, cooperation. This kind of relaiton make both interacting tribes stronger. 3. Spread of diseases. This kind of interaction helps to improve the immune systems. Since year -10000, traces of Humankind are observed in all continents. Interation between tribes generates the culture. Tools ans languages are generated. More cultural tribes become stronter. Internatiola competition between tribes in technology generates various cultuires. \section{confuison with names} %In the old scriptures, in particular, in Bible, there are similar places. In the ancient time, there was no custom to cite related publications. In particular, The Panathenaic Games (566 BC - 393 AC), are easy to confuse with the Ancient Olimpic Games (776 BC - 393 AC); The authors, descrining Panathenaic Games seem to know nothnig about the Ancient Olimpic Games; and trose, who mentione the Ancient Olimpic Games, seem to know nothing about Panathenaic Games. The time intervals overlap; so, in principle the same sportsmen could participate both, in the Panathenaic Games and the Ancient Olimpic Games. In texts, related to the Grece democracy, the Panathenaic Games are mentioned. In antique Grece, the there was common practice to use only first name, mentioning someone. This cuses confusion. In particular, the Athenian citizen Hippocrates (5?? - 527 BC) is easy to confuse with doctor Hippoctrates (460 – 370 BC), lived in the next centrury and mentioned in the list of achievements of the antique world. The story about Athen democracy begins with old Hippocrates. The old Hyppocrates become known due to his son Peisistratos % Πεισίστρατος who uset to rule Grece in interval But in the story about Grece democracy, the Panathenaic Games are mentioned.
