cos the atmosphere filters out the long wave lengths which are the reds up to green leaving only blue indigo an violet which makes the sky look blue.

The sky is blue because the atmosphere tends to absorb other colors a little bit more then it does blue light; the result of this is that the intensity of blue light is great enough that the whole sky looks blue. Another way to say this would be that the sky scatters more blue light then the other colors.

It was Einstein who answered this question. It has to do with the way sunlight is scattered by the molecules in the atmosphere. Blue light scatters more than red (Tyndall effect also known as Rayleigh scattering), so more blue light reaches our eye.
There is an excellent description at the website listed below (look at the cartoon and it will be pretty clear).
It is not a reflection from the ocean. And it isn't just water molecules that cause the effect.

In order to understand why the sky is blue, first we have to understand why some things appear a certain color. Visible light is made up of all colors: red, orange, yellow, green, blue, violet, and everything in between. An object appears "blue" if it reflects (or more accurately, "scatters") more blue light than the other colors of light. For solid objects, those other colors are "absorbed", rather than scattered. For "clear" air, those other colors pass right through, without being absorbed. The sky is blue because the molecules of air scatter some of the blue light, while allowing the other colors of light to pass through. Why blue? Because the size of the molecules of air are close to the wavelength of blue light...about 0.0004 millimeters in diameter.

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

The sea is clear but loads of it causes it to appear blue and the Sun causes the colour of the sea to reflect into the sky.

Blue light is refracted more strongly than the other colors of the spectrum. Red through yellow-green light can pass through the atmosphere, but blue light is bounced around everywhere. The further from the sun you look, the deeper the blue gets. If you look near the sun, the yellow light can be seen.

Rayleigh scattering (named after Lord Rayleigh) is the scattering of light, or other electromagnetic radiation, by particles much smaller than the wavelength of the light. It occurs when light travels in transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering of sunlight by the atmosphere is the main reason light from the sky is blue.

Because it absorbs all colours of light except Blue. The colour of an object is the colour of the light reflected by it. THe sky reflects blue colour. So it is blue in colour

If the sky was green you wouldn't be able to see the trees.
