Answer:

Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic out gassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.

Explanation:

This is what I found but we all have our own opinions so it could be whatever theory you think is best. there is also the biblical way that states that God created the world and everything and then the scientific way is the Big Bang Theory and then we came along during evolution.

Answer:

If you want to know the scientific way the world started then that would be the big bang but If you want to know the biblical way the world started then God made the earth and all the things in it... It all depends on what you believe in because in todays world we still don't know the exact way the world started... I think that something really power-full made some of it at least but the world as we know it does not know. It changes each time some new innovation is thought up so I do not believe we know the true way it came into being.
