Santa Claus does not exist scientifically. Point one: the reindeer that allegedly pull the sleigh cannot fly so cannot get to rooftops. Point two: the bag holding all the toys isn't big enough for billions of gifts. Point three: Rudolf's nose doesn't glow red like a beacon. Point four: Even if all the other points were true, Santa doesn't have the time to visit everyone's home to deliver the toys. Point five: Santa's too fat to fit in a chimney and needs to see a cardiologist. Point six: Santa isn't a god like God so would be dead now anyway. Point seven: Santa is not God because a song lyric says to thank God that Santa Claus is coming tonight.
Pauli was wrong because it is wrong.
Now, don't ask me to prove anything about the tooth fairy or Big Foot or the Illuminati or Cupid or Icarus etc. People can imagine fanciful tales with splendor and magic, but it doesn't make them true.
