Yes the Hebrews say :
Overview
One of the most famous pieces of real estate on earth is the
Cave of Machpelah (also known as the "Cave of the Patriarchs") in the southern Israeli city of Hebron.
Machpelah means "doubled" in Hebrew. One reason given is that
four prestigious couples are buried there:
Adam and Eve, Abraham and Sarah, Isaac and Rebecca, and Jacob and Leah. (Our matriarch Rachel was buried elsewhere.)
Cave of the Patriarchs Significance
Yes the jews believe Adam and Eva are buried in the cave of Machpelah. Even stated it as so on a wiki article.
I guess they forgot about the flood and the Garden of Eden was in Iraq,
Its all about money, big bucks come from believing and preaching and writing books about the Bible and well sometimes countries as well.
