According to Bill Nye, aka "the science guy," if grownups want to "deny evolution and live in your world that's completely inconsistent with everything we observe in the universe, that's fine, but don't make your kids do it because we need them." -- Transcript: Denial of evolution is unique to the United States. I mean, we're the world's most advanced technological—I mean, you could say Japan—but generally, the United States is where most of the innovations still happens. People still move to the United States. And that's largely because of the intellectual capital we have, the general understanding of science. When you have a portion of the population that doesn't believe in that, it holds everybody back, really. Evolution is the fundamental idea in all of life science, in all of biology. It's like, it's very much analogous to trying to do geology without believing in tectonic plates. You're just not going to get the right answer. Your whole world is just going to be a mystery instead of an exciting place. As my old professor, Carl Sagan, said, "When you're in love you want to tell the world." So, once in a while I get people that really—or that claim—they don't believe in evolution. And my response generally is "Well, why not? Really, why not?" Your world just becomes fantastically complicated when you don't believe in evolution. I mean, here are these ancient dinosaur bones or fossils, here is radioactivity, here are distant stars that are just like our star but they're at a different point in their lifecycle. The idea of deep time, of this billions of years, explains so much of the world around us. If you try to ignore that, your world view just becomes crazy, just untenable, itself inconsistent. And I say to the grownups, if you want to deny evolution and live in your world, in your world that's completely inconsistent with everything we observe in the universe, that's fine, but don't make your kids do it because we need them. We need scientifically literate voters and taxpayers for the future. We need people that can—we need engineers that can build stuff, solve problems. It's just really hard a thing, it's really a hard thing. You know, in another couple of centuries that world view, I'm sure, will be, it just won't exist. There's no evidence for it.

Headline Tag: Science Rating: Amazing Hits: 1166 Comments: 3 Carl Sagan: Future of Humanity Carl Sagan: Future of Humanity "Those worlds in space are as countless as all the grains of sand on all the beaches of the Earth. Each of those worlds is as real as ours. In every one of them, there's a sucsession of incidence, events, occurences which influence its future. Countless worlds, numberless moments, an immensity of space and time. And our small planet, at this moment, here we face a critical branch-point in the history. What we do with our world, right now, will propagate down through the centuries and powerfully affect the destiny of our descendants. It is well within our power to destroy our civilization, and perhaps our species as well. If we capitulate to superstition, or greed, or stupidty we can plunge our world into a darkness deeper than time between the collapse of classical civilization and the Italian Renaissaince. But, we are also capable of using our compassion and our intelligence, our technology and our wealth, to make an abundant and meaningful life for every inhabitant of this planet. To enhance enormously our understanding of the Universe, and to carry us to the stars." Carl Sagan explains the immensity of space and time.
