Historians consider the biblical account of Noah and the Deluge as a myth. However, this famous event occurred at the earliest times of recorded history (Sumerian King List). Today scientists believe in the last ice age called Pleistocene ending in 10,000 BCE, but there is no witness of this planetary cataclysmic event and its existence is based solely on the controversial interpretation of its consequences and their dating. The existence of erratic blocks and the disappearance of mammoths are presented as evidence of the last glaciation. However, despite dating obtained by 14C (calibrated by dendrochronology) is considered absolute by most experts its confrontation with the Egyptian chronology, in which some dates are fixed by astronomy, reverses this widespread belief and shows that dates obtained by 14C increase exponentially before -2200. Thus the rate of 14C tends gradually to 0 around -3500, which implies an important consequence: before -3500, 14C dating is no longer possible.
