You are quite right, and every answerer up till now is wrong. Simple mathematics shows that the farther distances are exactly compensated by the extra number of stars at each farther distance, so that the night sky should be ablaze with starlight.
This is called "Olbers' Paradox" and it has bothered astronomers for nearly 200 years. See if the Wikipedia article helps you understand it.

The intensity of light emitted by all stars in the space is not enough to illuminate the space in the night. This is because of very large distances between the two stars. The dist. of our Sun from Earth is 1AU, and the atmosphere gets illuminated in day time. But the dist. of nearest star Serius is more than 3 Light Years, whereas it being a white dwarf can't emit light as like Sun. Therefore eventhough there are trillion billion million stars in the sky they can't illuminate it in the night time. Otherwise there wouldn't be night.

The night can't appear to be day bcoz:
(1)the stars which are visible to our naked eye are far distant to our Earth.
(2)some stars which are nearer to the Earth may not have high intensity so that they can glitter at night.
If we approach (not possible)to another solarsystem,there, our beloved SUN may appear to be a minute star due to the factor of distance. that is the case why trillions & trillions of bright stars cannot illuminate the night like a day.

To be a bit more quantitative, the intensity of light reaching decreases as 1/r^2, and since most stars are many many light years away, the brightness of the stars are more than compensated for by the large distances involved.

I guess they do to some extent they are brighten Alaska and northern areas of the world. Another reason is they are so far away. It does seem odd that there so many yet their effect is subtle. Go to Alaska or Arizona in the summer when the moon is full and the stars are bright it almost seem like another world.

As they are many many light years away from us,their light is not enough strong to travel uptil sky and lit the sky....if you wish to see their powerful lights then you will have to go to the galaxy near them...!!

This depends upon the density of light they emit.

They are WAY too far away to make night appear as day. Our closest star is our lovely sun, but we've all evolved (or been 'created') to need the night (to rest and heal these ol' bods of ours).. So please don't wish it away!

cause they are spread out over the entire...universe..and we cant see the entire universe..at the same time..so wwe cant see.all of them..and secondly...they are so far..that even god wouldd think twice to go to them!!!!!!!!! and yes just imagine yourseif away fromthe sun...wouldn't it look smaller and less brighter....think about it

It's because of distance...
