You believe in the nebular theory
The nebular theory describes the formation of the solar system as a nebula cloud that began to collapse under the influence of gravity. As it began to collapse, it began to get more dense and hotter, which eventually formed a star. This star, the Sun, was at the center. While all of that was going on in the center of the nebula, the outer, cooler parts of the cloud began to form a swirling region of matter, which formed the planets and their moons through what we call star formation.
This theory originated in 1734 from a Swedish scientist and theologian, Emanuel Swedenborg. The work might have originated from Emanuel, but Immanuel Kant, who was familiar with Emanuel's work, developed the theory further and eventually published it in his work called the Universal Natural History and Theory of the Heavens (1755)
