The Garden of Eden in the Torah

The Torah begins with an idyllic, harmonious description of the creation of life in the Garden of Eden.
Why is Gan Eden not a central feature of the rest of Torah? Why is there no attempt of people to find it? Only Lot seems to search for it.

In fact, the major personalities do seek it, but it is no longer called “Eden:”  life in Eretz Yisrael is meant to recreate the Garden of Eden, but with a major difference: no easy irrigation source(a deliberate contrast with Egypt and Mesopotamia). We must recognize our dependence on God and cultivate a dynamic relationship. The goal of the Torah is to return to the harmony of the Garden of Eden in the Land of Israel, where life of blossoming and blessing is dependent on commitment to God.
