Good question! I'd like to go back to 2000-2001 when I was a newbie and read some of my opinions from back then. Have not figured it out yet.
Perhaps you could post a topic in the search bar and find an old topic there.
I decided to test my idea. I entered the word volcano, and after going back 15 or 20 pages arrived at 2002. Actually I had seen a few old dates mixed with newer dates. Like a 2003 article in the 2017 batch. So here is a link I found about what volcano might have caused Exodus. The article’s guess was Santorini. Mine is Etna.

You’ll need to file a FOIA request to make Google and the CIA cough them up. :)
