That was approx 3 billion years ago.
A new study suggests a primordial Earth still in the process of forming, clearly well prior to any life-forms first appearing. The 'land' was still a sphere of molten magma thousands of miles deep. When water did start appearing on the surface it was a piping hot magma ocean and yep it would have certainly boiled Noah and his family alive like a lobster, but lucky for him no life forms had ever ever appeared much less any type of trees and animals. ;0)
3 billion-year-old Earth had water everywhere, but not one continent, study suggests | Live Science
The Bible is still not a science book or even historically accurate on events for that matter.
Facepalm.
Do you know what biological memory is?
You see, before Noah, they had Utnapishtim in Mesopotamia. And in other countries all over the world, they all remembered when Earth was flooded. What you're talking about with magma and such was the Hadean period. But there wasn't as much water as steam then. The real flood of the Earth was during the Silurian period.
No, the Bible is not a science book. People have told you this before.
Do you actually know what a myth is? It's not "something that isn't true".
A myth is a way of encoding data in a story. The data is nor always "scientifically accurate" because " scientists " themselves are not always "scientifically accurate." Here's an example. Before the Big Bang theory, scientists used to believe ( in conflict with Genesis) that the universe always existed. Now they don't. So whether something is scientific or not is like a fashion trend. Who cares? A myth, or the other hand, tends to focus not on scientific accuracy, but rather in conveying other truths. For example, many of the myths of Coyote refer to specific animals being around. Guess what? These are constellations. You can pin down dates by these stories. Likewise, the story of Osiris (was it) being divided into pieces and then becoming whole matches the number of phases in the moon, with him becoming completely gone, and completely whole at the end. But while these talk about the natural world, that same story talks about the notion of resurrection.
