I have very little interest in it.
I'm posting on the winter solstice, and I wish to note that axial tilt is the reason for the season. Our planet's equator is tilted about 23.5 degrees to its orbit plane, and that's what makes the seasons.
Why do we make lots of light? Because that's what we are short of.
Why do we have Xmas trees? Because they look alive rather than dead. That's what "O Xmas Tree" is all about.
It's hard to tell what people were doing before they had written records, but what they built can sometimes give some hints.
5200 years ago in Ireland: Newgrange Stone Age Passage Tomb - Boyne Valley, Ireland - a broad mound with a tunnel into it that is aligned to the winter-solstice sunrise.
6900 years ago in southern Germany: Goseck Circle: The Oldest Known Solar Observatory | Ancient Origins - a circular palisade with openings in it:
