So, day and night are caused because the earth makes a full rotation on its axis once every 24 hours.
That way, have of Earth is facing the sun (it is morning on that side) and the other half isn't (which is why it is nighttime over there).
For example, if it's nighttime in Canada and America, it's morning in Pakistan and India. This is because Pakistan and India are facing the sun whilst Canada and America are not.
