Imagine if you will, some sixty million years ago, that a comet or asteroid did not wipe out the dinosaurs. Where would they be now in their evolution? Not the ones that turned into birds, they're useless, I mean some properly big, pointy toothed beasts. Would they have conquered space yet? Builder Adam Dodge has visualized this for us, and I think it would have been pretty impressive. The bigger question is would they have used a puny human to test their equipment in the early days?
