Sunlight reaches earth's atmosphere and is scattered in all directions by all the gases and particles in the air Some have answers, and some do not Blue light is scattered more than the other colors because it travels as shorter, smaller waves

This is why we see a blue sky most of the time.
The blue of the sky is not merely decoration—it has shaped life itself
The scattering of light influences climate, weather, and even the behavior of organisms. So, in short, the sky is blue because of rayleigh scattering, which causes shorter blue wavelengths of light to scatter more than other colors Our eyes are tuned to see blue more clearly, and the sun emits more blue than violet light, which is why our daytime sky isn’t purple. So, the sky appears blue because the molecules of nitrogen and oxygen in the atmosphere scatter light in short wavelengths towards the blue end of the visible spectrum.
The color of the sky depends largely upon the wavelengths of the incoming light, but air molecules (mostly nitrogen and oxygen) and dust particles also play important roles When the sun is high overhead, the bulk of its rays intercept the atmosphere at nearly vertical angles. In short, the sky looks blue because the blue portion of sunlight is much more likely to bounce off the molecules in the atmosphere than the other colors of light. Discovering why the sky looks blue, why sunsets glow red and how light scattering shapes earth’s colors and even skies on other planets.
The sky appears blue to the human eye as the short waves of blue light are scattered more than the other colours in the spectrum, making the blue light more visible.
To truly understand why our sky is blue, we must first embark on a journey through how light behaves, how our atmosphere works, and how our eyes interpret the grand ballet between matter and electromagnetic waves.
