The sky is not blue but our eyes are tricked into seeing it that way. Earth's atmosphere consists mostly of nitrogen molecules and oxygen molecules bouncing around as a gas. Air is close to perfectly transparent. Technically, the short wavelengths that scatter across the sky correspond to the colours blue and violet. However, the cone cells in our eyes that detect colour aren't very sensitive to violet, so we see the sky as blue. Despite the atmosphere containing so much air, it does not contain enough air to scatter 100% of the light and therefore act as opaque. We thus see the sky as a whitish-blue semi-transparent layer.
Most scientists define wetness as a liquid's ability to maintain contact with a solid surface, meaning that water itself is not wet
