You misinterpreted the entire Biblical story of Noah. When the ark rose high above the earth it meant it hovered in the air. From one earth to another earth. The previous Earth was what we call today "Mars" and it was destroyed.

It was a story about space travel, not one planet.

That is why they found water on the planet called Mars.

There was a rainbow in the atmosphere of Earth when Noah landed because he was on another planet.

Noah is a space dude. Same with his children.
