The exact wording was:

#1 – They Sailed Across Open Ocean With No Land in Sight

Roughly 60,000 to 65,000 years ago, humans somehow got to Australia. Not by walking. By crossing water they could not see across, in a direction that offered no guarantee of anything on the other side.

Researchers studying the migration have confirmed people were using boats and making blue-water crossings this early, with the southern route involving an open-water voyage of around 60 miles or more. That’s not a short paddle – that’s a multi-day commitment to a horizon with nothing visible on it. Scientists studying the genetics of the crossing describe it as not one-off accidental drift, but some of the earliest evidence we have for deliberate seafaring.

Fast Facts

Timing: roughly 60,000 to 65,000 years ago

Minimum open-water distance: around 60 miles with no visible land

Destination: Australia, reached before most of Europe was settled

Genetic evidence points to deliberate seafaring, not accidental drift

The unsettling part: we still don’t know exactly which route they took, how many boats were lost at sea before one succeeded, or what convinced an entire population to gamble everything on open water.

What part is opinion? They've used genetics to show that the bones found in Australia (destination) have the same DNA as the bones found at the origin of the journey.

It is open water with no land in sight.

Even if they saw birds flying, they likely had zero knowledge of migration patterns involving undiscovered land. In fact, they had no complete maps of earth at all. For all they knew, nothing was there where they set sail.

They are not supposing their thoughts, reasoning, methods, or even their routes, only that they HAD to have made the journey using some kind of boat for the DNA to be a match between places.
