Or it is just a mirror?

The sky appears blue for a combination of two reasons. Before white light reaches the Earth’s surface, the light waves collide with and bounce off of the nitrogen and oxygen atoms in the atmosphere. Different frequencies of light (in other words different colors) are scattered differently. Higher frequencies (blue and purple) are more easily scattered and thus bounce around in all different directions more than lower frequencies (red or orange) do. The scattering of high frequencies alone would cause the sky to appear blue and purple, but our eyes work better at frequencies near the middle of the spectrum (yellow and green). Since the color blue is closer to yellow or green than purple is, the sky we see appears blue.
The sky is not a mirror because if that were so it would be shattered by incoming meteors and we would all be sliced to ribbons.

the sky is blue during most of the day because light molecules refract off the molecules of air in the atmosphere causing all the colour changes that are visible, the amount of atmosphere the light has to travel through affects the colour, hence the reds and yellows in the morning and evening.
water is blue because the colour of water is blue, not because of the sky. If you've ever been in an indoor swimming pool with white tiles this point is illustrated.

It's the way light diffuses in the atmosphere and which wavelengths get filtered out. It's why our sky is blue and the sky on Mars is reddish orange and so on...
The different composition of gases in out atmosphere make it appear to be blue.
It's sad that you would think that there was some magic mirror up there with a blue tint to it. Where did you learn such a concept?

I believe the sky appears blue because blue is the color that our atmosphere reflects when light touches it. It also reflects other colors, depending on the amount and type of dust in the air.
Shouldn't this go in the science section?

My daughter who is in 4th grade here in the Middle East has told me that the sky isn't actually blue, but it is a reflection of the oceans. I studied in private schools in US for 12 years and I never knew that. By the way, 84 was my grade senior year. Best years.

The particles in the atmosphere reflect blue light from the sun thus making the sky blue. Even on a cloudy day.

I asked a school teacher why the sky is blue and he told me the answer was too far above my head.

the sky APPEARS blue because the gasses that make up our atmosphere allow red wavelengths of light to pass through while reflecting the shorter blue wavelengths....

Umm... bit of both?
It's blue, but mostly due to scattering... so you could say it's reflected light (kinda like lots of small mirrors)
EDIT

Oh man...did I miss the semanitc argument? Were you going to say "HAHA!!! so you DO believe!" or something moronic like that?

No, the sky has no color. It reflects blue during daylight, yellow/orange/red during twilight and dark/black at night.
