The boundary conditions are somewhat porous here. Take a look at the related page [1] about proto-writing. I think to some extent there's a philosophical and ontological frame that you have to put at the boundary; personally, I'm more inclined to add some slack into my understanding to accommodate for new artifacts we find that push back the earliest artifacts of recorded history. Still, even now, we have evidence of proto-writing at 6600BC at least (Jiahu shells), as well as the Vinca script and Dispilio tablet around 5200BC.
Thinking about this stuff stirs the same childlike wonder I used to have as a kindergartener thinking about dinosaurs and trying to comprehend or imagine what life must have been like so many millions of years ago. I very selfishly hope (but have no proof) that we will find earlier and earlier evidence of proto-writing. What a grand mystery and story!
The Tower of Babel story comes into pretty good context when you realize that the people writing it down (most likely in the 5th-6th century BC in Babylon) were living among the ruined towers of a Babylonian empire from a millennium before them.
