Why is the night sky dark?

If there is an infinite amount of stars...which is a fact well-known...shouldn't the night be uniformly bright? Especially since there is nothing in space to stop the light from getting to us, even if it is millions of years old? If there are an infinite amount of stars, then that means that there must be at least one in every spot around the earth at some point. So why don't we get their light?
 
because morning goes first then night thats why its dark at night because there is no sunlight or light
 
After 400 years of debate on the question, there is now fairly wide agreement among astronomers: there just aren't enough stars in the observable universe to fill up the night sky.
We don't really know how many stars there are. What we do know is that however many there are, we can see only a finite number of them.
The oldest stars are about 10 billion years old, meaning that the greatest distance starlight can have traveled is 10 billion light-years. So the only stars we could possibly see are those within a 10 billion light-year radius of us--the light from stars farther away has yet to reach us. The few jillion stars in our corner of the cosmos (AKA the "observable universe") don't have the collective candlepower to illuminate the night sky. (True, as time goes on, light from more distant stars does reach us, but meanwhile some close-in stars are dying out.)

So that's why the night sky is dark.
 
Read up on Olbers Paradox, and its solution.
It will really help to understand this.
 
But they are NOT evenly distributed.
Above the north pole for example are almost no stars at all.
The Milky Way is a BAND of stars and that area is much brighter
than other areas.
 
"If there is an infinite amount of stars...which is a fact well-known..."

Well, there ISN'T an infinite number of stars...which is a fact well-known to most...
