It is believed that the Nile River is the oldest river in the world, according to the National Park Service. However, several other rivers may also have a claim to the title.
In addition to the Nile River, the Finke River in Australia claims to be the oldest river in the world based on geologic evidence. The Tigress and Euphrates Rivers also make this claim based on the viewpoint that civilization began on their banks. The New River, which flows through West Virginia, is believed by many to be the second oldest in the world. However, it is possible that the Colorado River, which created the Grand Canyon, is older.
