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).
yeah and what’s crazy to think about is that we’re probably at a point where it took 4 billion years to go from bacteria to humans but it will probably take less than a few million years to settle most of the milky way.
But a few hundred to create our own mass extinction event
