Jerusalem's Critical Evidence?

Seldom does a "terminus post quem", the earliest date an item came into existence, and a "terminus ante quem", the latest, perfectly sandwich the artifact to define its absolute archaeological age. 

In ancient Jerusalem, on Mount Moriah's eastern slope, a crucial study by Weizmann Institute, Tel Aviv University and Israel Antiquities Authority dated evidence in a drainage channel, beneath and above a plaster layer that was built on top of clay-rich, virgin soil in a natural bedrock cavity. 

Directly beneath the plaster (its earliest date), small charcoal flecks were dated separately (sample 10293 and 9965) between 1615–1545 BCE, a "terminus post-quem" for plaster in the channel. At the bottom of the channel, above the plaster (the latest date) several grey and white laminations were found with charred material (sample 9964 and 10292), "ante-quem", understood to represent the channel was last used between 1535 and 1445 BCE.

During these approximately 100 years the drainage channel was used to propel water (by gravity) onto the bedrock floor of at least one of two rooms of the Temple Zero complex immediately below (east of) AreaU. In each room slaughtered animals would have frequently been processed and offered as a sacrifice, thus requiring water be flushed via the channel to clean blood and excrement. Almost 600 years later similar hydraulic systems were engineered and used in the first and second temples further up the mountain.  

According to Biblical chronology Jacob and his family arrived on Mount Moriah in 1553 BCE then left the region in 1523 BCE and lived in exile, in Egypt, where they remained for 210 years before the nation journeyed back to their land. The overlapping 100 year use of the drainage channel with time of Jacob makes this discovery remarkable particularly because of its potentially exciting context to the Temple Zero location.

In the Biblical context of Area U, the rock-cut-rooms of Temple Zero and the Gihon Spring, Bible commentators relate events of Adam, Noah, Shem or Malchi-Tzedek, Abraham, Isaac, Jacob, Joshua, King David and subsequent kings. Spanning thousands of years, the area on Mount Moriah is also referred by many names including; Salem, Beit El, Yireh (Yireh-Salem), Luz, Tzion, Jebus, City of David and Jerusalem. 

Immediately after King Solomon, King Jeroboam mis-directed and split the nation in part by leveraging confusion over Jacob's Beit El. Therefore, his actions and motivations must be understood before one can truly appreciate the magnitude of  discoveries being made at Temple Zero, Jerusalem. The recently discovered, possible City of Ai (associated with Beit El) is located just 1.3 kilometers east of  Temple Zero, resolves Jeroboam's Bethel ruse, 17km north, establishing Jerusalem's Temple Zero the exclusive, common Beit El of Abraham (Genesis 12:1-8, 13:3-4) and Jacob (Genesis 28:11, 35:14).

By aligning the city of Ai and Biblical events with the 100 year overlapping use of the drainage channel, confidence rises that Temple Zero is the location Jacob erected the recently discovered matzevah on which he made a covenant, to which he returned and accepted upon himself the name "Israel". 

For the modern nation to rediscover the original beacon, erected by Jacob on which he accepted the name of their national identity would be nothing short of miraculous, perhaps too much for the archaeological fraternity to acknowledge.
