This article is pretty cool. It explains how, while studying ancient tools on Okinawa Island, Professor Yousuke Kaifu wondered how early humans managed to reach such remote places 30,000 years ago. To explore this, he and his team recreated a possible Paleolithic sea voyage by paddling a handmade dugout canoe from Taiwan to Japan’s Yonaguni Island — a tough 140-mile journey across the powerful Kuroshio Current. They crafted the canoe using replicas of ancient stone tools and carefully planned their route using natural elements like ocean currents and seasonal patterns. The trip took 45 grueling hours, with the team battling waves, bailing water, and navigating by reading ocean swells when stars were hidden. Their successful voyage, published in Science Advances, challenges the idea that early humans were primitive, showing they were capable of impressive feats with simple tools and deep knowledge of nature.

So yeah this is preety cool :D
