Does anybody know how the
universe is formed? Why Earth is only suitable land for life? When firs man
appeared? All these and lot more of these kinds of issues are huge questions with variable answers and only small number of people know some answers, but generality they are still wondering. Or,
simply they leave answers aside and accept only the information which can be
substantiated with evidence.
What is well-known today is that
the man, even long time back then, was a social being and he could not live alone. For that purpose, people were
grouped in small
groups called tribes. The tribes had own certain rules that have had to be
respected by everyone in that community. This way, the tribe provided safety
of each member, which was the most important thing for each unprotected individual.
