According to www.todayifoundout.com when light from the sun enters our atmosphere it collides with molecules in the air.
The blue part of the light gets scattered more than the other parts during these collisions and thus makes the sky appear to our eyes as blue. If the light from the sun took a straight path down to our eyes with no scattering or absorption in the atmosphere, the sky would in fact look much as it does at night in the day time, which would be kind of awesome in my opinion.
