•This represents the life of our earth on the scale of a 24-hour clock
•Earth is an estimated 4.567 billion years old
•An exact order of events and their timing is not possible. These numbers are based on what we know right now.
•On this 24-hour scale:1 hour=190 m.y.every minute=3 m.y.every second=53 t.y.
