Sunlight is older than you think

Portrait-oriented dramatic movie poster, 1024x1536. Large, bold, fully legible title at the top 20 to 25 percent: "The 250,000-Year Journey of Sunlight" in a thick cinematic display font, high-contrast white text against a dark glowing solar background, the title is the only text. Below, show a majestic cutaway of the Sun with a blazing core, a dense radiative zone filled with winding photon trails like golden sparks in a storm, and a small bright beam escaping into space toward Earth. Add Earth faintly below with warm sunlight touching skin and leaves, cinematic lighting, rich gold, orange, and deep black tones, realistic science-documentary style, vertical composition, dramatic and awe-inspiring, clean layout with no extra words.

Deep inside the Sun, fusion in the core forges energy, and those photons begin a long random walk through a radiative zone so dense that they can take about 170,000 years to leave it.

NASA describes this as a random walk problem, because photons are scattered again and again before they ever reach the surface.

The sunlight warming our skin today is actually ancient. 

While it takes only about eight minutes for light to travel from the surface of the Sun to Earth, the photons themselves are created deep within the Sun's core. Because the core is so dense, these photons bounce around and can take up to 250,000 years to reach the Sun's visible surface before making their quick trip to Earth.

I heard that the light from nuclear fusion reactions in the Sun's core takes about 200,000 years to reach its surface. I thought the speed of light is constant. Why does it take so long? | Astronomy.com
