Thanks for this interesting read @agbona!

The existence and supply of water vapour in the atmosphere is the reason behind the planet’s weather condition.

Correct, and the Earth's magnetic field is the reason the planet has an atmosphere. (Well, the reason it hasn't lost its atmoshere to be more precise). What we don't know for sure yet is what generates the Earth's magnetic field, however we do suppose that it's caused by inductive currents flowing from the core towards the mantle.

I just enjoyed your post so much!

Keep up the good work!
