Dear Sapiens, You forget that God told us how this happened more than 3k years ago. Human blood was contaminated with the blood of the sons of God (prehistoric people) when Cain, on Adam's earth, and Noah's grandsons of the present earth, produced children with prehistoric people who were NOT Humans. (descendants of Adam) Gen 6:1-4
Since NO man of the time could have possibly known about genetics, this is evidence that ONLY God could have written Genesis. The FACT that all knowing scientists have yet to learn what cost Humans some 90% of our lifespans, shows the backward knowledge of today's "so called" scientists.
It seems they cannot read Gen 2:4-7 which tells us that Adam, the first Human, was made Billions of years BEFORE any other living creature, thus making it impossible that Humans could have evolved from ANY other creature.
