Using the Gregorian calendar, Noah would have been born in 3078 BC. His father Lamech was born in 3255 BC and was 182 years old when he had Noah.
As a newborn Noah was prophesied to bring comfort. God was pleased with Noah, so he chose him to build an ark in order to preserve life in a time when the earth was full of wickedness and violence. His responsibility was to save the animals and his family from the 40-day flood. Noah was 600 years old when the flood began. He lived another 350 years after the flood ended.
