What’s interesting about this is that these painting occurred in the same time frame as the cave paintings in Germany.
The reason this is interesting is that 40000 years later european Sailors get out to Hawaii and other pacific Island within a thousand years of Polynesians arriving from north of Australia using ships with similar technologies navigating by way of similar insights into the stars.
Its almost as if at the deepest level humans all over the planet have been progressing at roughly the same speed—even without interaction.
One look at Europe vs. Africa when the latter was discovered by the former would convince you differently. When Europeans set foot on islands so close to the African coast that you could see them from the mainland, they were the first homo sapiens to have done so.
If two disparate populations discover the same technology at roughly the same period of time, the most obvious reason why would be some form of communication between them, rather than divine providence.
