Re: Flores Island has 800,000 year old artifacts
The earliest known humans in Africa date from 200,000 years ago, so Flores Island must have a WAY bigger mystery than what happened to the missing boat.

Canoes are seaworthy, and the only thing they had to carry was the occupants with their skills. It wasn’t a pleasure trip.
Earliest known humans at 200K ago is and always has been British-born out-of-Africa nonsense.
