I am the third from a sparkle bright. I thrive throughout the day and night. Deep in the path of a cow's white drink. I've had thousands of millions of years to think. But one of my creatures is killing me. And so the question I ask to thee, is who am I?

Earth

Why this is the answer

Earth is the third planet from the sparkling sun, sits within the Milky Way ("cow's white drink" is milk), is billions of years old, and is being harmed by humanity, one of its own creatures.
