Edge of the Earth

As I understand it, Noah wasn't a sailor or even near the sea. The story simply involves making a container or box that would float. There is no evidence of it being a ship, or capable of travel. So the edge of the world would probably not have been considered.

Never, I don't think it had never crossed his mind, because he had his full trust in God and that he felt that God would lead him to wherever until eternity. He trusted God and felt that God had trust in him, so he only followed orders and did his best to lead everyone else to survive the big flood.

I guess if he trusted that God wanted him to build an ark because a flood was coming, when they had never even seen rain before, he figured surely God wouldn't let him die after doing all that work.

Not really because I think back then those who followed G♥d knew the earth was round. From what I heard, Job is older and in the book of Job is where it says the earth is round, so Noah probably had no fear and trusted G♥d completely..
