'Did you know that geologically, the Susquehanna River is considered the oldest major river system

in the world? It dates back to the Paleozoic Era (543 to 248 million years ago), and there is evidence that the flow of the ancient Susquehanna was established early enough that it predated the formation of the Appalachian mountains over 300 million years ago.

It is merely a contender for world's oldest river. See:
https://en.wikipedia.org/wiki/List_of_rivers_by_age

The river usually listed as the oldest is actually the Finke in Australia (of course, it is usually just a dry riverbed).
