What scientific event is thought to have formed our solar system?

The formation of our solar system is primarily attributed to processes that began after the Big Bang, which occurred approximately 13.8 billion years ago. The Big Bang theory describes the initial singularity that expanded, leading to the formation of the universe. As the universe cooled, matter began to coalesce under the influence of gravity, eventually forming stars, galaxies, and other celestial bodies, including our solar system.

Following the Big Bang, around 4.6 billion years ago, a cloud of gas and dust, known as a solar nebula, collapsed under gravity to form the sun and the surrounding planets. This process underscores the significance of the Big Bang as the foundational event that set the stage for the existence of our solar system and everything within it.

Other options refer to different concepts or philosophies. The First Cause is a philosophical argument related to the existence of an initial cause for everything in existence, but it does not specifically detail the scientific process of solar system formation. Evolution pertains to biological changes over time and does not address how celestial bodies originated. The Genesis Creation is a religious narrative about the creation of the universe as described in certain religious texts, which is not scientific evidence but rather a theological perspective.
