Some 4.5 billion years ago , our solar system began to emerge out of a dense cloud of interstellar gas and dust.
This cloud collapsed into a swirling disk of matter that got hotter and hotter and hotter until hydrogen fused into helium.
And just like that , our sun was born .
And baby Earth was on its way to .
After the birth of our stars, all the matter on the farthest ends of the spinning disk began to clump together.
These lumps would be the seedlingg, for the planets and moons in our Solar System.
As they accumulated more matter , they grew bigger and more sphercial.
The clumps in the cooler regions of the Solar System , were mostly made of ie , liquids and gases.
Closer to the Sun, all the rocky material formed the inner planets like Mars and Earth.
This Young Earth was incredibly active, volcanically speaking.
It spewed out gases like hydrogen sulfide , methane and carbon dioxide.
These gases made up the very first atmosphere on our planet.
Early Earth was constantly bombarded by large asteroids and comets.
And soon Eardh experienced an even more violent collision.
Theia, a planet the size of Mars , slammed right into our young world.
This epic collision threw hunks of matter , all round Earth”S orbit , and then gravity bound them together into what we now know as the Moon.
