Finke River
A river in Central Australia whose course predates the mountain ranges it cuts through via incised meanders, a pattern that only forms if the river was already there before the ranges rose. That implies a drainage system at least as old as the Alice Springs Orogeny (roughly 400-300 million years ago), often cited as one of the oldest rivers on Earth - a claim the sources themselves call plausible rather than provable.
