The Sunlight Reaching Earth Is About 30,000 Years Old
While light takes 8 minutes to travel from the Sun's surface to Earth, the photons themselves were created in the Sun's core tens of thousands of years ago.
About this fact
Photons generated in the Sun's core undergo a 'random walk' as they bounce off dense plasma particles, taking an average of 30,000 to 170,000 years to reach the Sun's surface. Once they escape the surface, they travel at the speed of light, reaching Earth in just over 8 minutes. So, the light warming your face today began its journey long before human civilization.
