nebular hypothesis
The Nebular Hypothesis.
The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests that the Solar System formed from nebulous material.
The solar system is believed to have formed about 5 billion years ago, and by the way, why do you call it YOUR solar system? Do you come from a different solar system? Because if not, then it's OUR solar system.
