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).
The Sun contains approximately 99.86% of all mass in the solar system… everything else is 0.14% orbiting it. Of that 0.14%, the Earth is only a 0.22% fraction.
The Sun loses 130 billion metric tons (130 trillion kilograms) of matter to the solar wind every single day, that’s 260 times the mass of all currently living human beings every single day.
Yup it’s tossing off all that entropy and life is able to locally reverse some of it temporarily
