Earth’s energy balance is driven by the Sun. The amount of heat leaving the planet, has to average out to be equal to the amount of energy incoming.
Solar energy reaches the ground and warms it. This heat in turn warms the atmosphere via conduction and absorption by greenhouse gases. All of that heat has to return to space, via radiation, convection, evaporation in the lower troposphere, condensation in the upper troposphere, etc. Essentially all of the heat is dissipated into space by greenhouse gases in the upper atmosphere.
Without greenhouse gases, atmospheric physics doesn’t work at all. That is why people who don’t accept greenhouse gas theory can not participate in the discussion. It is like trying to design a building without accepting the existence of gravity.
