40 centuries in less than 40 seconds

Today the scientific world is divided into 2 groups:

1-The supporters of the theory “evaporation-condensation-rain” in 3 step.

2-The supporters of the theory "evaporation-decomposition-compression-ionization-synthesis (H₂ + ½ of O₂ → H₂O )- rain" in 6 steps.

What group do you belong to?

I am the leader of group 2.
