Which is the earliest version of the Our Father?
The earliest version is found in the Gospels of Matthew (6:9-13) and Luke (11:2-4). Scholars debate which Gospel is older. The doxology (“for yours is the kingdom, the power, and the glory . . .”) is not found in Luke and is not found in the oldest surviving versions of Matthew. The oldest non-biblical reference to the Our Father would be The Didache (which does include a doxology).
