If Life Began 24 Hours Ago

A lot of you might have heard this before, but it's still worth mentioning. The Universal Clock is a thought experiment that scales the history of the Universe and separately of the Earth to a 24-hour clock. So if the Big Bang (or the formation of the Earth) happened at 12 am and right now was 12 pm, when would the major (on a scale of the Universe) events happen?
