The stardust is a given. As for sunlight, all the energy including somewhat arguably geothermal (using the suns gravity to help form the earth and I guess radioactive material being formed by other stars) comes from the sun and gets converted into chemical energy you eat so you’re stardust animated by sunlight (mainly).
so … you’re saying that earth will eventually slow down the spinning until its angular velocity equals that of the rotation of moon around earth?
That is accurate. However, there is also an effect from the Sun. I think the Sun will do it first, but I have not checked.
