AGWSF's basic fictional meme here is «all electromagnetic energy from the Sun is the same and all create heat on being absorbed» — this is the meme you are repeating in your «Without sunlight adding energy which converted into heat».

They have done this primarily by the same technique used to change real gases to ideal for the same reason, to get rid of real world properties and processes which real world physics knows and has defined by the distinct differences and similarities, which knows that electromagnetic energies from the Sun are not the same and do not all create heat on being absorbed.
