Yes Adam and Eve lived around 5000 B.C. . . . if you believe the Biblical account and just add up all the generations to work out a date.
So everything before then, Dinosaurs, Neanderthals and all the rest, gets squeezed into the seven days bit. And since Adam witnessed the ccreation of ALL the animals, and his actual life span given in years, then those seven days had to be literal days.
Maybe God had a pencil and an erasor. ANd dinos and neanderthals lasted but one day.
