Primarily because the atmosphere refract all other wavelengths away from us, but the blue component is less refracted and passes down to our eyes.
In the evening, as the angle of the sun decreases, we see the other colours coming out. The pressure and atmospheric water also affect this, so some sunsets are redder than others.
We also see red light reflected off clouds once the sun has passed below the horizon, which can confuse the issue.

Because from the light spectrum blue is the only band that passes and all the other colors gets filtered.
