    Thunder and lightning occur at about the same time. Lightning is an incredibly hot electrical discharge that occurs when opposite charges build up inside clouds or between clouds and the ground. The air around the discharge is heated almost instantaneously to about 50,000°F (five times the temperature of the sun’s surface). When the air is heated so quickly, a violent expansion creates a shock wave in the air around it, much like that of an explosion. This wave travels through the air, carrying vibrations to your ears, where they are perceived as the sound of thunder.

    I think you mean why do we see thunder then hear it later. The reason for this is due to their speeds. The speed of sound is around 725 MPH or mc.1. Speed of light on the other hand is like 350,000m/s a second or close to that. This is why you see the thunder and then hear it later.

    Because our ears sense sound and our eyes sense light.

    For a given event you will see the light before the sound reaches you.
