Now Noah was six hundred years old when the flood of water came upon the earth.
*******************************
It would have taken his family 500 years to build the craft... makes sense.
Did the Bible say that Noah was 100 when they started building the ark?
==============================================
The problem with that is the first planks put in would have already ROTTED away long before the 500 years needed to build it.
What? Did Noah have the "rock people" working hard for him?
Noah also spent 120 years warning people,and asking them to repent. Call me arrogant, but IMHO, very few people have the kind of faith in God that Noah did.
