They believe the planets formed from a disc of gas and dust called a "protoplanetary disc".
dust and ice and other partcials
When the sun was being born, matter that was circling around it formed into planets. There was hundreds of planets, but most of them were destroyed when they crashed into each other. Eventually, only the main 8 planets were left. Then water came on earth from comets.(scientists think so anyway) and life was formed
i believe so because when you see a galaxy its more denser in the center so heavier elements. a solar system and galaxy are similar (when the solar system i being created) there for the rocky planets terrestrial planets were created first. Then gas planets took what was left.
Scientists believed that first the earth was a ball of fire. They believe that the earth formed around this ball of fire, thus meaning the ball of fire is the Earth's core.
We may possibly know how Earth was created.
first era was the Precambrian
PRECAMBRIAN :)a+

At the same time that the Earth (and the other planets) formed : 4.5 billion years ago.
Earth, along with the other seven planets in our solar system, formed around 4.6 billion years ago. Exoplanets, the planets orbiting other stars, would have formed at varying times in the past.
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.

Earth and the other planets formed around this time.

You need water to live and other planets don't have water
Scientist theorize that a planet-sized object collided with earth and the moon formed
The planets of our solar system were formed at different times, the earth is known to have formed as a planet about 4.6 billion years ago but other planets in the solar system may have formed earlier or later as they were quite conceivably not formed in the same manner as the earth
