Incidentally, the creationists that I've encountered diligently deny that our Earth's climate is being altered by people. This point of view and teaching is in absolutely no one's best interest. Here's hoping we can work together and preserve the Earth, for us - us humans.

I always liked show biz and got to make a few training films at Boeing.

No matter what you may believe spiritually or otherwise, the Earth is clearly not 6,000 or 10,000 years old.

To leave the world better than you found it, sometimes you have to pick up other people's trash.

Climate change is happening, humans are causing it, and I think this is perhaps the most serious environmental issue facing us.

I say to the grownups, if you want to deny evolution and live in your world, that's completely inconsistent with the world we observe, 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 engineers that can build stuff and solve problems.

Evolution is the fundamental idea in all of life science, in all of biology. The key to our being here now is time, 4.54 billion (Earth) years of time. Nuclear fission wasn't discovered until long after Charles Darwin and Alfred Russell Wallace published their original books and papers, for example. Our ability to measure atomic masses wasn't developed until long after their deaths. These features of nature enabled us to reckon the age of the Earth and compare it with speciation rates here.
