The Big Bang is believed to be the event that gave rise to the entire universe, including our solar system. According to the prevailing scientific theory, the Big Bang occurred approximately 13.8 billion years ago and marked the beginning of the universe as we know it. It was an incredibly hot and dense state from which the universe rapidly expanded and cooled over time.
Within the framework of the Big Bang theory, galaxies, stars, and planetary systems, such as our solar system, formed over billions of years through processes like gravitational collapse and stellar evolution. The specific formation of our solar system took place much later, about 4.6 billion years ago, through the accumulation of gas and dust in a rotating disk that eventually coalesced to form the Sun, planets, and other celestial bodies.
Therefore, while the Big Bang is responsible for the creation and expansion of the entire universe, it also set in motion the conditions that led to the formation of our solar system.
