Every one of us alive today is the front end of a line of survival and evolution that began with the first life on the planet.
Every one of us represents all our ancestors, all the way back to the beginning. We stand on their shoulders, increasing knowledge and understanding; we limit ourselves by clinging to their no-longer viable, and outright mistaken beliefs and habits. That’s something to think about, when we consider throwing in the towel, giving up, going under: That is the line we are finishing, when we bequeath an uninhabitable world to our children.
Each of us is like the meteor that streaks across the sky, ending an existence that goes back to the beginning of the Universe. Every body began and will end as star dust.
