Don't get too over-excited, keep the celebrations reasonably calm. By everyone's calculation the World is fairly old, so be careful with the World. Modern science has also found some significant related dates with the same pattern. My own research has led to the discovery of the following dates. Out of Africa - Groups of modern humans appear to have migrated from Africa at this time.
Archeological findings show artistic design features characteristic of modern humans.
This appears to be the time of separation of modern humans from Nearnderthals. The separation of human and chimpanzee lines of descent. The separation of the line of descent leading to humans and apes from one of the groups of monkeys. Our ancestors crawling out of the sea to be fully land based animals. Hence the celebrations this year.
