Why people see the same side of the moon?

Just like the sun the moon rises and sets...so as the earth rotates you see the same moon and the same sun it's just when the sun is on one part of the earth you see the moon and vice versa.....

Comment: I can't say that helps much, but I will not delete that answer. This is my answer:

People see the same side of the Moon because gravity has locked the Moon's rotation period at the same length of time as the time the Moon takes to complete one orbit of the Earth.

If you think about it, that means we must always see the same side of the Moon.
