A nebula ie a cloud of gas starts to collapse. The conservation of angular momentum result in that is spins. If you have a spinning cloud with particles that travel in random direction they start to collide.

The Short Answer

A nebula ie a cloud of gas starts to collapse. The conservation of angular momentum result in that is spins. If you have a spinning cloud with particles that travel in random direction they start to collide. A spinning direction will be dominant and a disc start to form Particles that have a another orbit then the disc will pass trough it and collide with it. so the only way to orbit and not collide is to be in the disc. Planets are formed in the disk so they will all be in the same plane.
