GOD created Adam on the sixth day of the week (06/01/00) ref-Genesis 1: 26-31.Then in Genesis 5:3-5 Adam (the begining of creation) lived 130 years, and begat Seth, that is the creation (130 years) when seth was. And seth lived 105 years and begat Enos (vs 6-8),the creation will be 130+105 # 235 years. Enos (vs 9-11 ) lived 90 years and begat Cainan 235 + 90 # 325. However by using the same method, we have 1231 year (from vs 12-32), so all the years will be 325+ 1231 # 1556 years from the creation. The flood started 100 years after Noah begat his firstborn 100+1556 # 1656 and ended a year later 1657, ref-Genesis 7 : 11 ; 8 :13-19. thanks
