It is believed that the first annual mammals - Australopitseki - appeared on Earth about 4, 2 million years ago. Then they gave way to a person skillful (Homo Habilis), and they were replaced by a man with his own (Homo Erectus). Finally, there was a turn of Neanderthal and a reasonable person (Homo Sapience).
Details The evolution of spinning mammals can be viewed in the diagram below.
So, judging by the above temporary gaps, another 5 million years ago could not go and speeches about any mammals not what could think, but even just walk on two legs or make the simplest weapon from stone and branches. At the moment it is the official position of archeology, confirmed by numerous studies and finds exhibited in museums around the world.
But among the skeletons of Neanderthal, the simplest instruments of labor of the first descendants of people, the most ancient prints on the clay dishes and other artifacts, there are also such finds, the existence of which science still cannot explain and the official recognition of which threatens to turn the entire historical picture of the world.
One of these finds is the imprint of the sole of a boot discovered on a stone in one of the mines of Nevada, USA. In October 1922, Engineer and Geologist John Raid explored rock rocks in one of the mines, as suddenly noticed an unusual stone right in front of him, on which part of the human shoe was clearly imprinted. Nothing - humanity is of shoes at least several thousand years, but only a preliminary analysis of fossils showed that its age is at least 5 million years. It turns out that long before the officially recognized appearance on the planet of the arms of the man's hands, someone, wearing shoes, came to the ground, which then hardened and turned into a stone.
The find was stated in newspapers, which immediately caused violent scientific discussions. The first thing specialists drew attention was the age of fossil. It was not clear why John Raid and scientists who conducted a study were given to finding precisely 5 million years old, although the stone was found in the rocks of a triad period, which took place about 200 million years ago. However, this remark only reinforced the disputes: even the assumption that 200 million years ago - during the time when the era of dinosaurs did not even even reached his heyday - the one who could wear shoes lived on the planet, seemed madness. Next, the scientific community pointed to the ovoid shape of the lower part of the "boot" characteristic of the natural formations of the nodules of Zheleznyak. Interestingly, those found elsewhere specified by their form really resembled a "shoe imprint from Nevada."
In addition, if you carefully look at the photo, it becomes clear that it is impossible to accurately determine the initial form of "boot" - his front part could be any: to continue for some time or end through a centimeter.
Determine the size of the boot, as well as the floor and age of the creature, to which he belonged would affect the sequence of steps, but it was not found.
However, the fact that the most question is questioned by the truthfulness of this story is the absence of accurate information from John raid about the location of the stone imprint.
It would seem that the theory of artificial origin of the "imprint" is completely refuted mainly due to lack of facts. However, during a few years later, the macro-photographs along the perimeter of the sole was found a plurality of grooves, which look like this line from threads fastening the sole with the top of the boot. Disputes about the Nevada fingerprint shoe broke out with a new force, and seemingly John Raid could simply give a stone imprint to specialists for repeated analyzes and studies, but he did not. The public was provided only by photographing and extract from the Rockefeller Research Institute, where the main study of the find was conducted.
Disputes about the fingerprint of a shoe from Nevada from 5 to 200 million years old continue to this day, but the vast majority of specialists are confident that this comfront on the stone really very much resembles the form of a boot, but still has a natural origin. And traces from threads are only traces of water penetration into cracks on the stone. But the main thing is that it interferes with the case to move away from the dead point is the absence of any data about the current location of the stone imprint. Perhaps his creators simply did not want to show the "find of the public" in order not to be fully exposed. Perhaps the imprint of the boot from Nevada did not specifically show the world: because if he is real, then the entire representation of mankind about the history of our civilization, the origin of man, and, perhaps, life is incorrect.
