An Ark is nothing more than a modern shipping container.
Do I believe the story of Noah?? No..sounds like artistic license at it's best.
The Bible is God talking. He dictated the various books to prophets who acted as scribes or secretaries and wrote it all down.
I would recommend believing God, because He has never lied.
All men lie, however. So, if you believe anybody believe God.
I don’t see how what you believe or don’t believe has any bearing on reality.
