Our appreciation of a sunset is in part because of our analytical faculties. Beauty is a quick way of measuring the rightness of a thing - for example, in people, we correlate beauty with physical health. Instead of assessing every single attribute, we roll it together into one measure - that of beauty. Sunsets are beautiful because they resemble the savanna of the Pleistocene epoch, where you were safe back at camp at the last light before the dangerous night arrived.

Though a cinematic sunset may have little impact on our survival today, there is an evolutionary benefit to us evaluating and appreciating 'beauty'.
