I calced that it occurred 9,472 years ago. When are these people going to learn to be exact...:-)
You have no monopoly on exactitude. After all, consider Bishop Usher who calculated that the earth was created at 2;30 pm on Dec. 23, 4004 BC (or some such similar exact date) based on his “careful” examination of the “begats” in the bible. Anyone who has read the bible knows that the various begats are only approximate, so how did he get so exact?
