A Quote by Sylvia Earle
If we could magically transport ourselves back to the young Earth, when it was only a billion years old or two billion years old or three billion years old or four billion years old, we wouldn't be able to survive. We would have a hard time surviving if we were transported to the time when dinosaurs were around.

When I was a child, the Earth was said to be two billion years old. Now scientists say it's four and a half billion. So that makes me two and a half billion.
Our galaxy is 10 billion years old. The Earth is only 4.5 billion years old. We are a firefly flicker in the great astrobiology of the galaxy.
The universe is eight billion years old, the last two billion of which have produced intelligent life. During this time not one hour of absolute equity has prevailed.
Our planet has been around only for four and a half billion years. Let's imagine a planet that has life on it such as life is on Earth and it's seven billion years old. Let's say that planet evolved intelligence. Well, that intelligence would be way more advanced than what we call intelligence here on Earth. How long has intelligence been around on Earth as we've come to define it?
Consider: Life arose on Earth close to four billion years ago. Four billion years of slithering, swimming, and soaring life forms. But only in the last 200 thousand years has a species arisen that can fathom the laws of nature and build hardware able to signal its presence.
As soon as the idea of the Big Bang was proposed in the 1920s, astronomers set about trying to work out when the bang happened. Initial estimates were, not surprisingly, wildly inaccurate, but by the 1980s it was known that the universe was 15 billion years old, give or take 5 billion years.
I remind myself that the universe is 15 billion years old, and I'm only 46 years old, so my perspective is sort of limited and fear-based and skewed.
I remind myself that the universe is 15 billion years old, and I'm only 46 years old, so my perspective is sort of limited and fear-based and skewed. So I sort of turn things over to whatever you want to call it - whether it's God, or the universe or the spirit of the universe - and I just sort of turn things over to God and hope that this spirit that has been around for 15 billion years will have a better understanding of how things should be than I do.
There are 6.6 billion people on the planet today. With organic farming we could only feed four billion of them. Which two billion would volunteer to die?
My fan base is really, really young. They're the youngest demographic that you can track on YouTube: 13- to 17-year-old females. But the fan mail that I get in my P.O. box, they're all from moms and from kids who are two years old, three years old, four years old.
We're a young species; We're only 175,000 years old. On the evolutionary scale, life on this planet is 4 billion years old. We're 175,000 years old. So we're trying something out. Who wouldn't think it would be better to have the most stuff to take as much as you could? As we do that, we see why the moral prophets come along and say, don't even store into barns, right? It's easier for a camel to pass through the eye of the needle than a rich man to enter the kingdom of heaven. We've seen we plunder nature. We plunder our neighbor. We create enemies because we're against each other.
Man's inhumanity to man is as old as humanity itself. Some people just do evil things. Most do not. A billion people have seen 'Batman' movies over the past 20 years, and they have been entertained and inspired. One man saw it as a sick entry point for mass murder. The one is tragic. The billion are not. I choose to write for the billion.
We might expect intelligent life and technological communities to have emerged in the universe billions of years ago. Given that human society is only a few thousand years old, and that human technological society is mere centuries old, the nature of a community with millions or even billions of years of technological and social progress cannot even be imagined. ... What would we make of a billion-year-old technological community?
The observations that have developed over the years have given us perspective about where we fit in. We are newcomers, really recent arrivals on a planet that is four and a half billion years old.
When we look out into space, we're looking back in time; the light from a galaxy a billion light-years away, for instance, will take a billion years to reach us. It's an amazing thing. The history is there for us to see. It's not mushed up like the geologic record of Earth. You can just see it exactly as it was.
The record of the rocks contains very little, other than bacteria and one-celled plants until, about a billion years ago, after some three billion years of invisible progress, a major breakthrough occurred. The first many-celled creatures appeared on earth.
