Using a timeline from LA to NYC, since you made me curious:
- life formed 3.7B of 4.5B years ago, which is 700km towards NYC from LA; or about Colorado
- proto-humans formed 2M of 4500M years ago, which is about 1.7km “from” NYC; a distance hard to compare with the whole way
- human lifespans are about 70 of 4.5B years, which is about 6cm “from” NYC; a distance hard to compare with either 1.7km, 700km for life to form, or the whole 3966km.
Ha! thanks! My memory of this was way off. But I guess I liked the idea at the time if I remembered it at all decades later. Life has been evolving for a LONG time.
