So a rocket moves by having a big explosion push it. A car moves by little tiny explosions moving things and then mechanics to get it to the wheels, how does light power itself to move? especially with how fast it moves?

Light is special because it has no mass. Light cannot be compared to other objects. Light can only ever move at the speed of light in whatever medium its traveling through. Light can never be still and it requires no acceleration to reach that speed. The instant it comes into existence, it’s moving at the speed of light. The laws of physics show that light simply has to move at that speed and it always does.
