I believe that there are 3 unique things that allowed life to form on earth.
1) Our distance from the sun and gravitational pull means its the right temp, the warm iron rich core allowed the formation of an atmosphere, the atmosphere keeps the water.
2) Jupiter. Its such a large planet it sucks in any potential disastrous asteroids that would have blown us into smithereens.
3) We did get hit by a heouage asteroid that tore the recently solidified crust from earth and formed the moon, The moon gives us tides this was essential in life moving from water where it started to evolve to produce lungs that enabled life to evolve on land.
None of this can explain the price of a pint.
