The meaning of life is not a question that can be answered because asking the question makes no sense. In case one in which there is a God, only God can ever know the meaning of life as such a concept would likely be beyond our mere human understanding, until we die and meet God himself thus allowing him to make us understand, if he chooses to do so. In case two in which there is no God, then you are presupposing that life has a specific, intended meaning, which presupposes that there was a creator to give life said meaning, which (in this case where it is known that there is no God) would be impossible.
