How was Earth millions of years ago?

The universe grew and cooled and eventually stars and galaxies formed. The Earth was formed about 4.6 billion years ago, that's 4,600,000,000 years ago. It was formed by collisions of particles in a large cloud of material. Slowly gravity gathered together all these particles of dust and gas and formed larger clumps.
