Hi, Pressie.

Sure, but I'm working within the confines of the OP's mythos. Presumably, the current sabbatical cycle began with Creation Week, which presumably lasted 7000 years (unless "1 day = 1000 years" is only meant to be applied when convenient). Since Adam was created during Creation Week, there would need to be an additional ~2.5 billion years
after Adam's creation before the Destruction happens, which means ~2.5 billion years of
human history.
That timespan for human history is not attested in either the geological record or the biblical record. In order for this numerology stuff to work out, either (1) we've got a long time to go before Destruction, or (2) there is some unattested "human history" somewhere; e.g., Adam and Eve lived alone in the Garden of Eden for billions of years before the Fall, or Adam's and Noah's biblical ages were given in
divine years (so Adam died at age 339,682,500), or something like that.
