Early attempts to explain the origin of this system include the nebular hypothesis of the German philosopher Immanuel Kant and the French astronomer and mathematician Pierre Simon de Laplace, according to which a cloud of gas broke into rings that condensed to form planets. Doubts about the stability of such rings led some scientists to consider various catastrophic hypotheses, such as a close encounter of the Sun with another star. Such encounters are extremely rare, and the hot, tidally disrupted gases would dissipate rather than condense to form planets.

The nebular hypothesis is the most widely accepted model explaining the formation and evolution of the Solar System.
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.
Depends on your denotation for the world. If your intended use of the word "world" is the Earth, then the Nebular Hypothesis for the formation of solar systems is more appropriate to explain the origin of planets, like Earth.
It was first proposed in 1734 by Emanuel Swedenborg. Originally applied only to our own Solar System, this method of planetary system formation is now thought to be at work throughout the universe. The widely accepted modern variant of the nebular hypothesis is Solar Nebular Disk Model (SNDM) or simply Solar Nebular Model.

The Earth's composition is more relevant to the the Nebular Hypothesis for the formation of solar systems is more appropriate to explain the origin of planets. However, the Big Bang creation event did provide for the matter and energy which eventually facilitated the formation of black holes, galaxies, solar systems and then the planets.
Planets do not evolve in the Darwinian sense, but they do form and change over time. The model describing how they form is the Nebular Hypothesis, first formulated by Emanuel Swedenborg and Immanuel Kant.
