Why are you hearing thundering after lightning?
A lightning flash travels at the speed of light. The sound of thunder travels much slower. Therefore, we see the flash before we hear the thunder.
A distant lightning can be seen several seconds before the accompanying thunder is heard. Why?

Why do you hear thunderclap after a lightning flash?
Because light travels faster than sound. So the light reaches you first then the sound comes after.
If the time lag between seeing the flash of lighting and hearing the thunder is 4 seconds how far away is the lighting?
Compare the speed of light to the speed of sound for your answer. In any explosion, you see the flash before you hear the noise.
Why does the flash of lightning take only an instant while the thunder can last for a few seconds?
The speed of light is much faster than the speed of sound. You see the lightening before you hear the thunder.
When a gun is fired its sound his heard a little after seeing its flash?
The light shown by the flash travels at the speed of light, while sound waves travels slower. It is the different speeds of light and sound that causes sound to be heard after seeing the flash.

Can light exist before sound?
Light can exist without sound. A fluorescent light is an example of this. But yes, light can exist before sound. Light and sound are created simultaneously by something like lightning. It's just that the light is propagated much faster than the sound. We all know that we see the flash of lightning before we hear the sound it makes, and we can "calculate" the distance to the bolt by simple mathematical means.
