We all know that there are a large number of stars in the sky, I would like to know what makes the night so dark?

The question you ask is an important one, for its resolution helped bring about the realization that the universe is expanding. The German astronomer Heinrich Olbers considered this very question in a paper published in 1826. There is not space enough here to do a proper job of answering your question, so I urge you to consult an astronomy text. This is a famous problem and should be treated in many books. Check the book's index for "Olbers' Paradox". For example, the book "The Unity of the Universe" by D. W. Sciama gives a detailed and not too technical description of the question and its solution (by the way, Olbers guessed at the solution but his explanation turned out to be wrong).
