According to theistic evolution, there must have been many thousands - possibly millions - of “soul-less” human beings in existence when God decided to inject a soul into one them - Mr. Adam. Then, presumably, all those soul-less humans - who had the same brain as Mr. Adam and who had been able to survive for millions of years - became extinct. How did that happen? How does 99.9999% a race of humans become extinct?
Furthermore, for hundreds of thousands of years, these soul-less humans would have had brains of more or less the same intelligence as Adam. So they would have developed writing and methods of recording history. So where is this recorded history? And why hadn’t they invented smart phones and aeroplanes? Or even the wheel?
