Okay, you have my attention. Where did you get your thesis?
Chevron (from the verb chet-beit-re'sh, "to join") is the location of the Garden of Eden, where the physical and spiritual worlds are joined. Abraham bought the Cave of Makhpelah to bury his family in because Adam and Eve were already buried there.
Of course if you're a Protestant or a Qara'ite this won't satisfy you.
