Noah’s Ark could have been round like a modern Fishing Bobber-Float, as per a newly translated Mesopotamian clay tablet in the British Museum
The ancient Mesopotamian tablet has instructions from God on how to create a floating vessel to save animals and people from a catastrophic world flood which would soon happen (in the ancient past). The animals are to enter the craft two by two. Similar to the story about Noah and his Ark, but this craft is round like a ball or like a modern Fishing Bobber.
