How can any river have originated after 21,000 BC, since that's when the last Ice Age was at maximum glaciation, and the ocean levels were 400 feet higher at that point?
Prior to 12,400 years ago and up until 23,000 years ago, there was an Ice Age. At 23,000 years ago, that's when the Ice Age was at a maximum, and the ocean levels were 400 feet shallower. This means that there was a lot more land, and more rivers in those days. Also, all of today's rivers are a subset of all the rivers that existed 23,000 years ago. **So are there any new rivers formed since 23,000 years ago, and if so, how did that happen?**
