Today  I went to SEODAEMUN  MUSIEM OF NATURAL HISTORY. I learn about universe and start of life. The universe was born about 15 billion years ago starting from bigbang.

  Bigbang is that tiny thing that like a ball have to be explored. And 4.6 billion years ago earth started. Earth spin around the Sun. Sun is fixed star, so many other plannet spin around the Sun. Mercory, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Nepturn.

  And time later then become a sea and First bactera name cyane live in sea. And there is evolution of sea and evolution of land so there live fish and crocodile and dinosaurs. The most smart dinosaur's name is Troodon.
