How did early man navigate the oceans without GPS?

Instinct seems like a error ridden approach to seafaring.

It’s not ideal, but it’s worked for our species so far.

Instinct is actually a more reliable approach to seafaring than a GPS device is, at least in the long run. A GPS device will fail if it loses signal, but if the sun or the moon goes out or if the wind suddenly changes direction, your instincts will fail with you.
