Ah, the fossils found in the Himalayas are over 15 million years old, so it had nothing to with imaginary Flood that happened (also imaginary) less than 4500 years ago.
Plus, if you understood fossilisation, there are no animals preserved in fossilized-state of less than 10,000 years old. Again that would also refute fish fossils being in imaginary Flood less than 4500 years ago.
Second. Book 10 in Genesis, clearly stated that Egypt didn’t exist before, but Egyptian civilizations predated the imaginary Flood over 600 years (eg 3100 BCE) and Egyptian culture by at least 1500 years. Take for instance, the first pyramid was built by Djoser from the 3rd dynasty, known as the Step Pyramid in Saqqara, hence predating the Flood by about 200 years (2670 BCE). (Note that the Great Pyramid was built in Giza for Khufu, in the 4th dynasty, but it wasn’t the oldest pyramid.)
The city of Uruk, which is known as Erech in other translations (eg KJV), was first occupied around 5000 BCE (hence around 7000 years ago), but Uruk was a flourishing Neolithic city, throughout the 4th millennium BCE, where temples to goddess Inanna, around 3500 BCE.
Uruk/Erech in Genesis 10, say that Nimrod built his city, which is certainly isn’t true, as of Babylon, Calah (Kalhu), Nineveh, and Asshur. Each of these cities were first constructed in different times, so there are no way that one person would have constructed these cities.
Like I said the first settlement in Uruk was 5000 BCE, while Calah/Kalhu was built by Shalmaneser I, around 1250 BCE. So unless Nimrod lived for about 370 years, I don’t think Nimrod is real person, therefore Genesis 10 is a complete myth, just Genesis 7 & 8.
