If you are familiar with their work, you must also be conversant with the numberless anomalies in stratigraphic layers when digs are done worldwide.
99% of fossils are marine life--much it found as high as the Himalayas, coincident with Flood theory.
You are completely ignoring that those "marine fossils" are over 30 million years old.
A jawbone of a whale was found in the Himalayas, and that was dated just over 53 million years old. Other marine fossils showed that some up dated even earlier than the whale jawbone, while others are dated to before 30 million years.
The date all predated the 3rd millennium BCE Bronze Age.
And the estimation of time to the Genesis date, using the Masoretic Text (Hebrew Tanakh or what Christians called the Old Testament) put it within the 2nd half of 3rd millennium BCE - meaning between 2499 and 2000 BCE.
I don't think those marine fossils on the Himalayas meet with date to the Genesis flood. The Himalayas may be younger than other ancient mountains, but they are not that young.
The Indian tectonic plate is still pushing into Asian plate, so the uplifting and folding is still causing the mountain to rise 5 mm per year.
Multiplying 5 mm with 4500 years, you would get 22,500 mm, which is 22.5 metres. So in 2500 BCE, Everest would be at 8826 m high, 22.5 m shorter than today's 8848 m.
So the Himalayas, including Everest, were still "very high" highland. The water in Genesis Flood would have to be over 8830 metres, so where would all that water come from, and where did the water go afterward?
Can you provide evidences or cite scientific (preferably peer-reviewed) sources that these fossils are less than 4500 years old?
