Actually... technically it doesn't.
What you hear is the shockwave caused when lightning instantly heats the air around (This can reach up to about 30 000 °C). That very hot air expands rapidly, then contracts as it cools. The rapid expansion then contraction generates sound waves, making the 'clap' of sound that we call thunder...
so the Lightning isn't making the sound it is the air around it that makes then sound.

Yeah, but lightning causes the sound.

Thunder is lightning, only at the speed of sound.. or something like that, innit?
