Hello, it means the darkness covered the entire world and then God created light, the suns light reached the earth, and the rays heated the atmosphere. This sounds like a strange question but think about it. Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.
