Before the Big Bang there was NOTHING AT ALL. No galaxies, no space, no light and no sound. Then suddenly, 13.8 billion years ago, IT ALL BEGAN… This beautiful book tells the story of our universe for young children. Travel back in time to the Big Bang, see galaxies and stars form, watch the birth of our planet and how life begins and join the first man on the moon! Welsh adaptation.
