The universe began with the Big Bang, a rapid expansion of space and matter from an extremely hot, dense state, and the Earth formed from a swirling cloud of gas and dust, the solar nebula, around 4.6 billion years ago. The Big Bang and the Early Universe: The Big Bang Theory: The prevailing scientific model explaining the universe's origin is the Big Bang theory, which suggests that the universe originated from a tiny, extremely hot, and dense state about 13.8 billion years ago. Expansion and Cooling: After the Big Bang, the universe began expanding and cooling, allowing for the formation of subatomic particles, then atoms, primarily hydrogen and helium. Formation of Structures: Gravity then played a crucial role, drawing together these particles and forming stars, galaxies, and eventually, the structures we see in the universe today. Formation of Earth and the Solar System: The Solar Nebula: Our solar system, including Earth, formed from a vast cloud of gas and dust called the solar nebula, which was a remnant of a supernova explosion. Accretion: Within the solar nebula, dust and gas particles collided and stuck together, forming larger and larger bodies called planetesimals. Planets Form: These planetesimals continued to collide and accrete, eventually forming planets, including Earth, around 4.6 billion years ago. Earth's Early History: Earth's early atmosphere and oceans likely formed through volcanic outgassing and impacts from comets and asteroids. Formation of the Moon: A major impact with a Mars-sized object is believed to have resulted in the formation of the Moon.
