Jomon artifacts point towards significant cultural transfer with the Black explorers who first peopled the Earth over 30,000 years ago. The styles are virtually identical to the type of art being produced in Africa in the same time period as the first great exploration.

What theory makes more sense?
That the Jomon just spontaneously came into existence, or that they were mainly composed of these Black explorers whose contributions have NEVER been valued by western academics? (I don't want to say it's for racist reasons but...)

What makes sense to you?
