PERSPECTIVE

In an earlier post about the Grand Canyon, I mentioned the age of a couple of the rock layers. Here are the years of some other things, living and non-living, in this universe.

First of all, the universe is 13.82 billion years old.

The sun is around 4.6 billion years old.

The Earth is 4.54 billion years old. The Earth’s moon is 4.53 billion years old.

The earliest evidence of life forms on earth is 3.8 billion years.

The schist rock in the bottom of the Grand Canyon is around 2 billion years old.

The limestone rock on the upper rim of the Grand Canyon is around 230 million years old.

The earliest evidence of Homo sapiens or modern humans, is about 164 thousand years ago. They were living on the coast in South Africa, where they harvested food from the sea.

The Industrial Revolution of coal, railroads, land clearing, agriculture and sanitation, about 200 years ago. (1800-1840)

The Industrial Revolution of fertilizers and other chemicals, electricity, and public health, about 100 years ago. (1870-1910)

World War I ended less than a 100 years ago. (1914-1918)

The Grand Canyon became a national park on February 26, 1919.

World War II ended about 70 years ago. (1939-1945)

Humans are one of about 8.7 million different species of the earth’s land and oceans. As of 2014, there are 7.3 billion people.

As I was processing these ages, I wanted to show how short our human existence has been. Our daily stresses are really nothing in this time thing. Enjoy your time.
