Someone else, maybe miamited?, was questioning you about this. Can you explain what you mean when you say there was no history before Abraham? Even in Scripture we have the accounts of creation (Genesis 1), creation of Adam (Genesis 1), creation of Eve (Genesis 2), birth of Cane and Abel (Genesis 4), the death of Abel (Genesis 4), the genealogy of Adam (Genesis 5), the great flood (Genesis 7), Noah's family by name (Genesis 9), the genealogy of Noah following the flood (Genesis 10), and so forth.I know that actual history began with Abraham. This means that there were persons around that took notes
or told oral stories to the following generations of actual events. What came before is prehistory and a lot of it
is hyposthesis. This does not mean it didn't happen -which I repeat constantly - but we also don't have detailed information.
Seems to be a lot of history.
