flooded a significant part of this densely populated region (fig.1). This submerging of 160 000 square kilometers was caused by a rapid rise of the Black Sea level with about 100 meters (Ryan et al. 1997, Ryan & Pitman, 1998, Dimitrov and Dimitrov, 2004). It left homeless and without food supply great part of the Indo-Europeans settled around the former sea coast. Therefore this most dramatic disaster in the human history forced them to migrate out of this dangerous region (fig.2). This way the Black Sea Flood played major role in the Indo Europeans history. The giant extent and consequences of this disaster along with the stunning coincidence of the dating of all processes discussed above allows relating of the Black Sea Flood to the Biblical (Noah's) Flood. Fig. 6 demonstrates that all oldest scripts have common origin, which was most probably located around the Black Sea coast. Later script was spread around by migrations of people from this ancient settlement. 6. Conclusions In conclusion we provided vast range of data demonstrating that the Biblical (Noahs) Flood story describes a natural phenomenon that happened in the Black Sea region at 56005500 years B.C., which initiated separation and differentiation of the Indo-Europeans in groups like German, Thracian, Illyrian, Greek, Arian, etc. tribes. It initiated the migration of Vedic tribes to India. Migrations from the Black sea due to the flooding of the region were extensive and far reaching. Presented data suggest that the Black Sea Flood may have been the Biblical Flood. Black Sea Flood triggered an outmigration from the Black Sea area into India with major repercussions for present population characteristics as established by comparative genetic studies ((Calafell et al. 1996; Vernesi et al., 2004; Quintana-Murci et al., 2004; Shopov, 2008; Dimitrov, 2009). 7.
