Earth was formed 4.6 billion years ago from the same nebula cloud of gas and dust that formed the Sun and other planets. Earth back then was very different from Earth now, and it would have been impossible for life to exist on it. The Earth is still changing even today. It has a molten layer, which causes volcanoes to occasionally erupt, and the crust of the planet is constantly moving, sliding over, under, and sideways against itself. Let's look at how the Earth may have become like the planet it is now.
