      Probably, I imagine most of the molecules your body is made from have previously formed part of an ancient creature, like a dinosaur. If you go even further back, I guess all the atoms we are made from originate from stars, so no doubt dinosaurs have been made from them too.

      Maybe, maybe not. The water you drank may have been locked away in an ice cap for millions of years, or been part of a deep underwater cave system. Water is recycled through clouds, rocks, soil, rivers and the deep ocean as well as through millions of living organisms in a huge continuous cycle but it’s hard to say where any one individual glass of water has come from.
