Well that's where the rubber hits the road, shubi. These things are spiritually discerned, I can't enlighten you. It's wisdom from above. If you are a Christian, and you study and you pray. it will likely come to you.
So, I assume you have no discernment in this matter.
The Spirit informs me that my previous posts are correct. There is no reason for the Ark story to be in the Bible, other than to scare people into believing in the Almighty.
That seems more of an Islamic doctrine than a Christian one.
In fact, the Ark story is more pagan than Christian and would appeal to Islam.
