Earthshine is the entire albedo of the globe. Something called the reflective quality of the entire planet including the atmosphere. Your attempts to separate out individual minor particles claiming some are more important than others is of no value to this discussion. We were discussing the entire "Biosphere" of the planet and not just some minor portions of it. Please try to keep up with the discussion here or keep quiet.
What I said was earthshine was due to sunlight reflected from the earth.
What is Earthshine
This is a smoky glow on the dark portion of the crescent Moon. It is caused by sunlight that reflects off the Earth onto the Moon's night side.
The long wave radiation emitted by earth is primarily emitted after having been absorbed. The longwave radiation at the top of the atmosphere is seen to follow a Planck curve characteristic of the earth temperature, showing that it is absorbed and re-emitted rather than reflected. Check out figure 1 of the following paper.
