It goes like this: The was a dense cloud of mostly hydrogen, and gravity condensed it until it heated up enough to start a nuclear reaction, and that was the birth of the sun. The leftover material condensed into rocks, which condensed into asteroids, etc., until gravity created the planets.
@ a24fan: That's mostly correct. The original Earth collided with another planet (not when the universe was forming, much much later) and the collision produced the earth we're on now, and the moon. Te original earth wasn't a jungle though, lol. Plants are lifeforms too.
