Anyone who tell's you other wise is an agent working for the Easter bunny.
That rabbit is a nasty piece of work, who's 1 intention is to wipe out Christmas.
He only uses "Easter" as a gimmick, to trick us into paying for him to kill unborn fairy babies, (yes, that's right, Easter eggs are murdered fairy eggs).
So if anyone says that Santa isn't real, report them to the police immediately.
I hope this helped.
