There is a list of things which the Bible and Jewish literature would have to know about if you wanted to believe that Adam and Eve were descended From Cro Magnons and which the Bible and Midrashim appear to know nothing about:
- Stone tools. Adam and Eve and their descendants were metal-tech people from day one. By contrast, human groups descended from Cro Magnons went on using stone tools until forced out of it by neighbors if they ever stopped at all. Aztecs were using stone knives and weapons when the Spanish arrived even though they used gold for ornaments and native Australians are killing kangaroos with such weapons now.
- The atlatl i.e. the signature weapon of the Cro Magnon people. The Bible knows nothing of this weapon; the weapons of the Bible are the sword, the spear, the sling, and the bow. By contrast, amongst Cro Magnon descendants, the Aztecs were using atlatls agains the Spanish and native Australians use it to hunt kangaroos today.
- Neanderthals and/or other hominids. The Bible knows nothing of hominids. By contrast, the Basque "Basajuan" appears to be a reflection of the Neanderthal and the Australian "Yowie" appears to be some sort of hominid.
- An upper paleolithic world war in which all hominids were exterminated from the planet.
- A "Purple Age", that is, a protracted age without any source of light such as we experience now, prior to the classical "Golden Age" of ancient literature. The Bible mentions the creation of light before the sun and moon are created and that the beginning is called an age when "the earth was without form, and void, and darkness was upon the face of the deep"; but Adam and Eve and the Bible antediluvians did not live on Earth in that age and the Bible beyond Genesis 1:2 does not speak of it again.
Likewise there is no version of anything which puts the metal ages prior to four or five thousand years ago which is ballpark for Adam and Eve and their descendants arriving on the scene.
There is a list of things which the Bible and Jewish literature would have to know about if you wanted to believe that Adam and Eve were descended From Cro Magnons and which the Bible and Midrashim appear to know nothing about: I don't want to hurt your feelings but the Bible does not mention a lot of things which nevertheless exist and existed.
And as far as no version of anything which puts the metal ages prior to four or five thousand years ago
Metallurgy was know to the neolithics of Catal Hoyuk as far back as 7,500 BC. Heck, nearby Gobekli Tepe dates back to 10,000 BC - double the antiquity you erroneously ascribe to the Adam and Eve story, unless you think Martians built it. But the Bible doesn't mention Martians either.
And of course you have Cro Magnon depicted what are now extinct cave bears, wooly rhinos and mammoths 25,000 year ago with a degree of skill that surpasses most of the "art" you find in contemporary primitive "descendants of Adam and Eve" cultures and what you typically find at MOMA.
BTW Stone tools. Adam and Eve and their descendants were metal-tech people from day one.
There is no mention in the Bible of metal before the birth of Cain's sons. Therefore, according to your own rules, it didn't exist on day one as you opined. But I'll let you in on a little secret. Metallurgy has been around for nearly ten thousand years, and whether it's on your list of things to know about or not is inconsequential.
