Simple answer: When the sun is out, the sky is brighter than the stars and all of the stars' light is drowned out.
Detailed answer: Stars glow during the day, but we can't see them because of the glare of sunlight. When the sun is up, the blue color in sunlight gets scattered all over the atmosphere, turning the sky the familiar bright blue color. This blue light is much brighter than the faint light coming from the stars, so it prevents us from seeing them.
If you were standing on the Moon, for instance, where there is no atmosphere, you would see the stars both day and night.

No, you cannot see stars from the bottom of a well during the day because the light from the Sun would be too bright to see the dim light of the stars.
The stars are always out just during the day you can't see them
During the day, the brightness of the sun overwhelms the light from the stars, making them invisible to our eyes.
no
It is not possible to see stars in the day due to the brightness of the Sun overwhelming their visibility. Stars are visible in the night sky when the Sun has set and its light does not interfere with seeing the stars.
Because the sun is brighter than stars
The stars are not visible during the day because bight sunlight scattered by the atmosphere masks the relatively dim light of the stars.
because the light from the sun is so close to us and so bright it blocks out the light from the other stars. The only time you can see light from other stars during the day is during a solar eclipse.
Because during the day - the Sun's luminosity is greater than the stars.
You can see the Sun - and that is a star. The light from the sun swamps out the light from the stars, (signal to noise ratio).
During the day, the bright light from the sun makes it difficult to see other stars. If we were to see stars during the day, we would see the same ones that are present in the night sky but they would be much dimmer and harder to distinguish due to the sun's glare.
Because the sun is far to bright in relation to the light from the stars.
