I loved dinosaurs, I loved space, and I thought maybe I'd be the first paleo-astronaut.

Sooner or later, we will face a catastrophic threat from space. Of all the possible threats, only a gigantic asteroid hit can destroy the entire planet. If we prepare now, we better our odds of survival. The dinosaurs never knew what hit them.

Asteroids have us in our sight. The dinosaurs didn't have a space program, so they're not here to talk about this problem. We are, and we have the power to do something about it. I don't want to be the embarrassment of the galaxy, to have had the power to deflect an asteroid, and then not, and end up going extinct.

I have no patience with dinosaurs.

Technology has a great advantage in that we are capable of creating dinosaurs and show them on the screen even though they are extinct 65 million years. All of a sudden, we have a fantastic tool that is as good as dreams are.

Dinosaurs was a cool idea, but we just couldn't find a way to make it really fun. We've got a bunch of great game ideas that we want to bring to life over the next several years.

Once in a while, I still witness occasionally sexist behavior and comments from men (which experience has taught me you should always deflect with humour rather than anger). Old habits die hard, after all, and it's unrealistic to expect dinosaurs to fall silent overnight.

Every day, hundreds of observations and experiments pour into the hopper of the scientific literature. Many of them don't have much to do with evolution - they're observations about the details of physiology, biochemistry, development, and so on - but many of them do. And every fact that has something to do with evolution confirms its truth. Every fossil that we find, every DNA molecule that we sequence, every organ system that we dissect, supports the idea that species evolved from common ancestors. Despite innumerable possible observations that could prove evolution untrue, we don't have a single one. We don't find mammals in Precambrian rocks, humans in the same layers as dinosaurs, or any other fossils out of evolutionary order. DNA sequencing supports the evolutionary relationships of species originally deduced from the fossil record. And, as natural selection predicts, we find no species with adaptations that only benefit a different species. We do find dead genes and vestigial organs, incomprehensible under the idea of special creation. Despite a million chances to be wrong, evolution always comes up right. That is as close as we can get to a scientific truth.

If you want to write a fantasy story with Norse Gods, sentient robots, and telepathic dinosaurs, you can do just that. Want to throw in a vampire and a lesbian unicorn while you're at it? Go ahead. Nothing's off limits. But the endless possibility of the genre is a trap. It's easy to get distracted by the glittering props available to you and forget what you're supposed to be doing: telling a good story. Don't get me wrong, magic is cool. But a nervous mother singing to her child at night while something moves quietly through the dark outside her house? That's a story. Handled properly, it's more dramatic than any apocalypse or goblin army could ever be.

Introspection and preserved writings give us far more insight into the ways of past humans than we have into the ways of past dinosaurs. For that reason I'm optimistic that we can eventually arrive at convincing explanations for these broadest patterns of human history.
