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).
True, sometimes as a joke when I’m meeting someone for the first time I’ll say “omg it’s been so live since I’ve seen you, like nearly 13.8 billion years since we met last”.
