Why did life develop on the Earth 🌎?

The origin of life on the Earth is a fortunate series of events. The Earth distance from the sun was such that its atmosphere and surface cooled down a moderate level. Liquid water and not just water vapour also formed, and it 

did not freeze as the sun was not to far away. The cooling of the Earth gave rise to a kind of 'primordial ocean '.The action of the UV rays of the sun 🌞 the lightning flashes produced by strms, and the countless volcanic eruptions gave rise to new complex chemical componds.

about 4billion years ago, the first molecules appeared, from which the first unicellular organisms were formed. Average distance to the sun:around 150million km

Radius:6378km 

Circumference:40,077km at the equator, 40,009km at the poles

During of one revolution around the sun:365.26days

Number of moons 🌙 1

Mass of the Earth 🌎:around 6trillion tons, I.e.,six followed by 21zeroes!
