I don't wish to argue your straw men. You are disproving the Bible by taking an age for the birth of Adam that I don't subscribe to. Google the discussions between competent Hebrew and Greek scholars on the issues.
Well, I don't think either Adam and Noah to be real historical people. To me, they are merely literary characters, made up mythological figures, that religious people believe in. And I have hard time believing anyone can live to 930 and 950 years.
And I don't think either events as narrated in the Genesis, thus the creation with Eden episode and the Ark event, ever took place.
But with the translations of the Hebrew Masoretic Text (MT) and the Greek Septuagint (Sept.), it is possible to work out backwards, from the time of Babylonian army sacking Jerusalem in 587 BCE (which was a real, historical event), all the way to creation of Adam.
Only the Orthodox Churches in the east, relied solely on the Septuagint, while the rest of churches (Catholic and Protestant) relied more on MT, but supplemented some passages on occasions with Septuagint.
Depending on which sources (MT and Septuagint) people use, the calculations of age to Adam's creation can be estimated approximately. There are several different manuscripts for the Septuagint, such as the Vaticanus Codex and Alexandrinus Codex, and the generations given in Genesis, differed in some areas, so they are not in agreement.
Although you can compare the Dead Sea Scrolls against the Masoretic and Septuagint, there is only fragments of Genesis 5 only 2 verses survive, and Genesis 11 is completely missing in Qumran's scrolls. Other sources include the Samaritan Pentateuch and the Vulgate Bible.
There are no other old sources but the bible and their various translations. And what we do have, we can estimate through a little research and using basic arithmetic.
Now I may not believe in everything Genesis say, including the ages of when they became fathers of their successors or when they died, we don't have any other information, other than the bible.
The Masoretic text, put it between about 2400 and 2100 for the Flood. While the Septuagint get much older dates, but they (remember there are main extant versions) put the creation of Adam around 5500 BCE, and the Flood to about 3258 BCE (5500 BCE - (Noah's birth 1642 AM - his age when the Flood occur 600)).
But dating the first Neolithic settlement of Jericho, still show it is even older than the Septuagint Adam's creation.
Whether Flood occur in 3258 BCE (according to the Septuagint) or 2340 BCE (as Masoretic say), it doesn't matter, because you are wrong that the Flood caused marine fossils being deposited at the Himalayas.
Remember this post, BB, you wrote (esp. highlighted in red):
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.
Those fossils you are talking about are older than 30 million years old. And the whale jawbone that I keep talking about, is 53 million years old.
There are absolutely no correlations between those marine fossils and your Genesis Flood. Man weren't around when these marine life became fossilised.
That's what I am arguing you were about. The marine fossils had nothing to do with Noah's Flood, and not by tens of millions between your biblical account and palaeontology.
Are you so blind that you cannot distinguish 53 million years (whale jawbone discovered in the Himalayas) from 5258 (Septuagint) or 4340 (Masoretic) years?
That's a huge gap between the bible myth and actual scientific discoveries.
