The most agreed upon answer is the one called accretion, and the idea is that gravity pulled together small pieces of rock and dust. Eventually enough material gathered together to create a considerable gravity well. There was a bit of competition for building material, as there were a few other planets trying to get stuff for themselves. The earth finally formed some 4.5 billion years ago.
