That's what Christmas is all about, Charlie Brown
For me ? More than just celebration of the birth of Christ (certainly MORE than the seemingly insatiable pursuit of trappings associated with commercialization), though I do profess that belief (just NOT a fundamentalist type). It embraces introspection. Nihilism vs. humanism (for short).
Whether "real", or "myth", Jesus Christ is/was representative of inspirational humanity. Celebrate that, in whatever manner befits your view of the world. MERRY CHRISTMAS to ALL ! L.
