But the men that had lived have thousand of years did not know the numbers nor knew to count. Then as they had appeared numbers? To answer to this question we need to have an idea of as these men lived and which were its necessities. At that time, the man, to feed itself, hunted, fished and harvested fruits; to live, he used caves; to defend itself, he used woods and rocks. But this way of life was if modifying little by little.
