meaning of existence

A deceptively easy philosophical question, and one of the two core concepts of existentialism, the other being our insignificance on the massive scale of the universe. The one answers the other: existence has no meaning. Meaning is a construct of our imaginations. It is inherently irrelevant to any philosophical discussion and should never be taken for a concrete fact. There you go. Jesus, guys, calm down now. It's not that hard.
