Miscommunication happens, and more easily when one tries to communicate with a language that is different from the one learned as a child.

It is true that man has made many things that convert the potential for energy into different types of motion, such kinetic energy includes IR radiation and heat which is an increase in molecular motion .

As I wrote in another post:
“The fossil fuels, bio fuels, and renewable energy sources such as solar and wind, all depend on the energy that originated in the sun, if we use these resources we can only extract, at the most, the same amount that came from the sun. (Actually far less because much of it has or will re radiate into space.)
During the eons of Earths existence the energy supply from the sun and the energy outgo from the Earth has balanced.”

I’m sure you are familiar with the water cycle diagram:

And the energy cycle in living things:

Or both combined:

These cycles have occurred on Earth for millions of years and during that time have been favourable for life on this planet.

I believe that if this balance is maintained, then life on the planet will continue for millions of years longer.
If the balance is disrupted, like it has been on the planets Venus and Mars, then life will come to an end.
My hypothesis indicates one possible way in which this balance may be disrupted.
