Geological Time Scale

Geological Time Scale puts things into perspective. The earth has been here for 4.6 billion years. Life (single celled creatures with no nucleus) began 3.8 billion years ago. Human civilizations have only been on earth about 10,000 years. The United States only 233 years. Marylhurst University 150 years. We, the students of ENV103A, less than 50 years.

What do you want to be remembered for?
