Forming of the sun (4.6 Billion years Ago)
The solar system started as dust cloud. 4,6 billion years ago a star nearby exploded, resulting in a shockwave hitting the dust cloud. This formed the sun -

History of earth

4550 BCE
Primary Accretion
Primary accretion is when dust collided with each other creating little clumps. After 100,000 years a rock was formed that could further grow. This process continued for another 10 million years. -
4540 BCE
Earth formation
It is believed that earth was formed by many collisions after the solar system was created. All these impacts increased our planet in size -
4500 BCE
Moon's formation
There was an asteroid that hit the earth that was roughly the size of mars, it didn't destroy the planet, but it did destroy itself and the earth's atmosphere. The debris of this asteroid left from the collision condensed into the Earth's moon -
4400 BCE
Core formation
After the collision, earth was very heated up. Later on, when the planer started to cool down, the lava became rock and liquid water started to condense. -
4000 BCE
Late accretion stage
Pluto-like objects crashed into planets - deposing metal in the surface of the planets. -
3800 BCE
Late Bombardment
Comets were hitting the planets, and it is believed that there was a comet carrying water that hit the earth which supplied the water supplies within eath -
1700 BCE
The big chill
The volcanic eruptions and rock weathering that accompanied the supercontinent breakup had trapped carbon dioxide, which caused the planet to significantly cool down -
1500 BCE
First life
This is when the oxygen and atmosphere levels rose, along with there being evidence of animals showing at the same timeline
