What is the first step in how our Sun was formed?
Clouds of gas and dust were pushed together, or attracted towards each other because of gravity, along with some energy waves (the Solar Nebula)
What is the 2nd step in how our Sun was formed?
Gravity pulled these materials in towards each other, eventually collapsing & things started falling towards the center.
What is the 3rd step in how our Sun was formed?
Things started spinning faster & faster creating a flattened disk.
