Until 6 billion years ago, there was no solar system or planet Earth. About 450 million years ago, a fiery sphere formed from dust particles, and boiling meteorites scattered throughout space. Then its surface took millions of years to gradually cool and form a solid sphere. The orb began to orbit the solar system, the head of the sun.

That nameless sphere we now call the earth has no grass or little life. At that time the earth was a floating rock with a diameter of just 7927 miles. The oceans formed on Earth about 100 years later.

The dinosaurs were egg-laying. The dinosaurs have ruled the world for 10 billion years. In addition, small milk-giving organisms also appeared. Although they are not all the fingernail size of a dinosaur, direct nesting is a marvelous phenomenon.
