Because the sun is so close to us compared to the other stars, its so much brighter. And all that bright sunlight in the daytime sky washes out any other star. All the other stars are just tiny pinpoints of light, even on a dark night.
The brightest object in the sky (besides the sun and the moon) is Venus - at its brightest it is -4.6. And the moon is -12.6. But the sun's apparent magnitude is -26.73 and that's 449,000 times brighter than the full moon.

The stars are always there, only different ones or different position from night as the earth from where you are rotates to face the sun. The sunlight hits the atmosphere and land in the day time with intense white light that cancells out the star lights, thats why you don't see any of them stars. However in the rare eclipse of the sun (the moon coming in between the earth and the sun), when the moon blocks out the sun light, you can actually see the stars in the day time as the sky darkens for a short while.

It's because of Earth's atmosphere.
The Sun is so bright that it illuminates the entire atmosphere via a process called Rayliegh scattering. That's what causes the daytime sky to be blue.
There is so much light in the Sun that even the small amount that is scattered into the blue sky is very bright, so bright that it overwhelms the dim light from stars. The contrast between starlight and scattered blue light from the Sun is nearly zero, so you can't see the stars.
If Earth had no atmosphere, you could see stars in the daytime; astronauts in space do so all the time.

11 wrong answers before Keith P gets it right. I'm just reiterating here to throw support behind his answer.
The light of the sun is scattered in our atmosphere causing it to glow bright blue. This bright atmosphere drowns out the light from anything else in space other than the moon, and maybe venus if the conditions are right, so that you cannot see anything. It is possible however to see bright stars in the daytime in a telescope, as well as planets.

Because the sun is so close to us that everything else is lost in its glare.
-edit-
After reading all the other answers, I did some research and to my surprise, Keith P (below) has it exactly right ... which means of course that I had it wrong.
Turns out, it IS earth's atmosphere that prevents us from seeing other stars during the day. If we were on the moon, we would easily see other stars right there along-side the sun, although the sun would still be the biggest and brightest of them.
The effect called "scattering" that takes place in the earth's atmosphere is what prevents us from seeing other star's during the daytime.
Thanks so much Keith P, for giving the correct answer below!

The sun is visible for #s of reasons:
-it's really bright
-it's the closest star (not planet) from planet earth
-the sun's light blocks out the other lights from the other stars, so that is the reason why we can't see any other stars. The other starts are actually there, we just can't see them. Therefore, when the sun sets (the sun goes to the other side of the earth) we can see the lights from other stars.

Because the sun is relatively close (93,000,000 miles away) it is so bright that it outshines anything and everything. At night, when the sun's light is blocked by the Earth, you can see other stars. If there's a full moon, you won't see as many stars, for the same reason -- the sun's light reflected off the moon still outshines most higher magnitude (dimmer) stars.

It's so near to us that it's light makes it impossible to see any other ones.
I know 93,000,000 miles doesn't seam near, but with a mass of burning gases that big, it's enough to cover up the light of stars a couple billion light years away.

The sun is no brighter than most of the stars we see, it's just MUCH closer to Earth than any other star.

Because it is very closer to the earth than all the other stars..
The sun is actually one of the smallest stars in the solar system..
