In our puny life times, we think of a couple of thousand years as a long time and that is not so surprising given the short span of our lives, usually less than a hundred rides on the merry-go-round and that’s it, you’re done.
Look at our history, a mere 500 generations back our grandfathers were just learning the art of growing food. Ten thousand generations back and we had only just become a clearly defined species in our own right, so how could we appreciate the passage of say, a million years?
If we struggle with a million, then let’s pretend that today is about a third of the way through the life of the universe. The Sun and the Earth are still six thousand million years in the future. Let’s just think about that again, not one million or a hundred million, but six thousand million years in the future. That’s when our Sun and Earth will come into existence.
460 million years ago, ocean plant life on the margins begin to colonize the land edges. Mosses, ferns evolve on dry land adapting to take moisture from rain.
The presence of plant life and oxygen create the required conditions for the first fire in our solar system. Eyes continue to evolve but only work in water.
