In Judaism, Christianity and Islam, the explanation (regarded as apocryphal in Western Christianity) is that knowledge of how to interpret times, signs and wonders in the skies was given to the people of Earth by the "watchers," who were supernatural/extraterrestrial/angelic beings, who ultimately came into opposition to God, due to their meddling and interbreeding with His creation. Land in the Antediluvian world was not separated by oceans; it was contiguous. The climate was quite different then, with rain being unknown and flora being nourished by mists that arose from the ground. So, in these religions, such knowledge should be present in all peoples, since it was taught prior to whatever caused the deluge and the breakup of what modern science has come to refer to as "Pangaea." The writings regarded as apocryphal by western Christianity that describe this are The Book Of Enoch (I, which has been confirmed as being authentic, having been found at Qumran, and not II, which is believed to have been written in the Middle Ages), The Book Of Jubilees and The Book Of Jasher.

Jasher and Jubilees are referred to by quoting from them in the Christian cannon.
They were considered cannon before politics took them out.

Any Mormon will smile and tell you about an ancient record that recounts the migration of a small colony of Jews from Jerusalem in 600 B.C. who came to the Americas. We take it as a matter of faith, that the Book of Mormon is a true record. It is always interesting to see the odd "coincidences" that appear as archaeologists discover such odd items as clay pan pipes tuned to the musical scales of the Mediterranean area or something like this supernova drawing. Someday, historians will recognize the connections between this colony of Israelites, the peoples of the ancient Americas, and the inhabitants of the Pacific Islands.
