Light is really just energy travelling through space in discrete amounts. We see the results of this energy, but we don't see it by itself. In fact, we can't even say where a photon is with certainty, we can only state a probability of where it will be.
Consider throwing a rock. The energy was transferred from your body to the rock, but does the energy really exist from it's frame of reference? Light is similar to this, except instead of a rock it is travelling in what we call a photon, and instead of going faster if I throw it with more energy, it will travel at the same speed but it will have a different wavelength.
