“It’s like when you’re a kid. The first time they tell you that the world’s turning and you just can’t quite believe it because everything looks like it’s standing still. I can feel it. The turn of the Earth. The ground beneath our feet is spinning at a thousand miles an hour.

“All over the world fools are poised, ready to let death fly. Machines of death screaming from above. Light brighter than the sun. Not a war between armies, nor a war between nations, but just death.

“It came because it couldn’t stand to watch your children cry. What if you were really old, and really kind and alone? Your whole race dead, no future. What couldn’t you do then?

“Our lives are important — at least to us — and as we see, so we learn… Our destiny is in the stars, so let’s go and search for it.”  – 1st Doctor
