0084 Of course, there is an explanation for why our current Lebenswelt is not the same as the Lebenswelt that we evolved in.
The explanation is called the hypothesis of the first singularity.
The hypothesis is plainly laid out in The First Singularity and Its Fairy Tale Trace.
The hypothesis is dramatically rendered in An Archaeology of the Fall.
The hypothesis is reflected upon in Comments on Original Sin and Original Death: Romans 5:12-19.
0085 Here is a snapshot.
0086 There is a reason why all the origin myths of the ancient Near East depict recent creations of humans. The myth tellers cannot see beyond the time horizon set by the first singularity. In particular, the people of the Ubaid, then Uruk, then Sumerian Dynastic archaeological periods in southern Mesopotamia could not remember the Lebenswelt that we evolved in.
The Creation Story is the sole exception. But, it does not stand alone. The creation of Adam and Eve immediately follows the first chapter of Genesis, giving the impression that Adam and Eve are the first humans.
Consequently, humans are created twice in Genesis 1-4. In Genesis 1, humans are created as images of God in an evolutionary framework. In Genesis 2.4-3, the preamble to the creation of Adam clearly places the Garden of Eden at the confluence of four rivers, including the Tigris and Euphrates, during the Wet Neolithic of southwestern Asia.
