Einstein’s Theory of Relativity states that light (as it is travelling obviously at the speed of light) is so fast that it experiences no (zero) time. Obviously light does move a distance, as thats how we see things as the light bounces off of objects into our eyes, but surely with the equation ‘distance = speed\*time’ and time being zero it implies light doesn’t travel any distance?

That’s not correct. It does not experience zero time. Time does not apply to light. If you put c speed into the time dilation formula you get division by zero not zero. In the theory of relativity you cannot construct a reference frame that moves along light because that would make speed of light to be zero in that frame and that is prohibited.
Light **alone** cannot be used to measure time and distance without other tools that don’t move at the speed of light.
