My point: The earth is a globe, and although we think of it as having a determinate, unmoveable top and a bottom, with "the top" being "north" and the "bottom" being "south, that doesn't seem to be the case throughout the eternity of ages the earth has experienced.

What is now Alaska has been shown to be tropical at some point in time. I am forgetting if it was hundreds of thousands of years ago, or millions.

What is north doesn't have to be "north" if you are looking at the globe some millions of years ago.
