In tribute to scales:
If year would represent a millimeter:
Human life was about 8cm long.
Birth of the Christ was merely 2 meters away and the first Homo Sapiens about
45 meters away. 
Last ice age was about 12 meters away and last mammoths about 4 meters away.
America was discovered about 50cm "ago" and first humanoids appeared on earth
about 4km away. 
Dinosaurs and the like rule the earth from 65km to 300km away. 
First organisms are born 3500km away and the earth itself, about 5500km away. 
Universe itself is approximated to is born 20000km to the past and our sun
will consume its fuel in about 5000km to the future.

My life is only 3.3cm of that.
