The very first Egyptian dynasty is usually considered to be Dynasty 1 which begins when Egypt is reunited by Narmer(Menes).Dynasty 0 represents a predynastic time in Egypt where either the unification of Upper and Lower Egypt had yet to take place or where Egypt was in the process of being united for the first time. The kings of Dynasty 0 are the least doccumented of all Egyptian periods and it can be believed that some of them may be completely myth and never existed.
