How long ago was the earth formed

The earth was formed 4.6 billion years ago.

what role did mass and gravity play in Earth forming?

As the earth gained more mass it's gravitational pull increased

When the sun cooled it formed meteors. With each strike Earth's gravitational force grew which drew more and more meteors to the planet. This eventually formed the Earth's layers.

The Earth got its atmosphere from many places as such as:
Volcanoes and plants. Volcanoes produced heat which evaporated the water into oxygen. Plants take in CO2 and give off oxygen too!
