Earth is the beautiful planet we live on. But it wasn't always that way. Imagine Earth, but it's very hot and uninhabitable. Let's go through the old days of the Earth.

The Earth has just formed. Let's see what's going on here.. Volcanoes.. Lava.. Meteors, and plain destruction. Also there were no continents. As you can see in the picture I conviniently placed next to this text, it's just land scattered across which actually look like big islands. Later the "big islands" will turn into big continents. I mean, what do you call giant land masses that aren't continents?

The first life forms were cells with the purpose of living. They were even smaller than bacteria. They later became Eukaryotes, which are basically cell groups, allowing us to live and develop organs.
