The same reason why most things happen; gravity. Every speck of matter in the universe attracts every OTHER speck of the universe with gravity. So a a large thin cloud of gas in space will, over time, become a smaller thicker cloud of gas. Given enough gas and enough time, the cloud will collapse under its own gravity to form a star, or a planetary system.
But if all the gas is attracted in all directions, why would it all fall together HERE, rather than OVER THERE - and since the gas is all over, why would it collapse at all? We think that the shock of a somewhat-distant supernova explosion begins the collapse process by pushing enough gas together for gravity to finally do its thing.
