      I think for me the most surprising thing has been to discover how different the Earth was in the past. We think it’s normal for our planet to have liquid oceans and mountains and animals and oxygen in the air. But at times in the past, Earth was covered in ice, sometimes had no mountains, and long ago had no animals or oxygen. Weird!
