Nebula
Scientists believe that the solar system formed from a vast cloud of gas and dust, called the solar nebula, around 4.6 billion years ago. Gravity caused the nebula to collapse and form a spinning disk, with the Sun forming at the center and the planets forming from the material in the disk. This model, known as the nebular hypothesis, is supported by observations of other planetary systems and the composition of the solar system.
No one knows it. Scientists lie or exaggerate about knowing. Although the above is partially true, scientists do have theories about how the solar system was formed. If the entire solar system was formed at the same time then all objects in the solar system are the same age. Using radioactive dating of meteorites scientists calculate how long it has been since the meteorite solidified and go based on that date.
Scientists believe that the solar system formed from a spinning cloud of gas and dust known as the solar nebula about 4.6 billion years ago. As the nebula contracted under its own gravity, it started to heat up and flatten into a disk. The center of the disk eventually collapsed to form the Sun, while the remaining material in the disk coalesced to form the planets, moons, and other objects in the solar system.
They really can't guess, since it was obviously millions of trillions of years since the Big Bang, which formed the Earth and began the Universe expanding. But not everyone believes in the big bang religious beliefs say that God created the Earth and the Universe.
Astronomers believe that the solar system formed from a giant rotating cloud of gas and dust called the solar nebula. As the cloud collapsed under its own gravity, it began to spin faster and eventually formed a flat, rotating disk. The Sun formed at the center, while the planets and other objects in the solar system accreted from the material in the disk.
Scientists believe that the solar system formed about 4.5 billion years ago.
by a theory of the BIG BANG explosion and the HELIOCENTRIC theory,that until now is being believe
The solar system is believed to have formed about 5 billion years ago, and by the way, why do you call it YOUR solar system? Do you come from a different solar system? Because if not, then it's OUR solar system.

Because there's no other plausible method for it to take place, and because similar processes are being observed even now.
Scientists believe that the Earth was formed around 4.6 billion years ago through the accumulation of dust and gas in the early solar system. This age estimate is based on radiometric dating of meteorites and rocks from Earth.
i believe mercury
Jupiter
They believe a large gas cloud in space was condensed into what we now call the sun. Chunks of this cloud flew into orbit around the sun and eventually condensed into planets.
4.5-5 billion years old

Scientists believe that asteroids originated from the leftover material from the early solar system's formation, primarily from the asteroid belt located between Mars and Jupiter.
