Ancient descriptions of beginning of the Earth and the global deluge are relevant to the Earth history. Beginning of the Earth or beginning of the time appears to be the beginning of the Supercontinent cycle on the surface of the Earth around 2800 million years ago. Since then, six Supercontinent cycles were completed on the surface of the Earth and the present is the seventh cycle. Global deluge appears to be the description of the rise in sea level occurred with the breakup of each Supercontinent. Therefore global deluge occurs in the beginning of every Supercontinent cycle. Descriptions of the Manvantara cycles, seven Earths and seven Karshvars are similar to the Supercontinent cycles.
