He can get around the world in one night, think of the different time zones, I saw a video from 1955, and his sleigh was in the air flying, and then the cameras went off, every person in the video was SHOCKED! I'm 16 and just started to believe again.
Saint Nicholas was definitely real, and he MAY have flung that dowry down the chimney (for more reference, read the story). However, the modern day present delivering being is a myth. There are currently 576,000,000 christian kids under 14 in the world. Thats 6,100 kids a second. Good luck. Not including the non christians, and the kids who believe in santa, but are homeless or never get gifts (no access to toy drives). I suppose they don't matter. And how does he get supplies, food (for the billions of workers required), travel undetected, and use only 12 reindeer (he would need over five hundred million). Oh yes, he also seems to have lived centuries. How.
The idea of Santa comes from religion, because it comes from someone named Saint Nicholas who was very generous to the poor. So they created the idea that were was someone who dressed up during Christmas and was giving presents to all the children across the world. However, there is no man actually doing this and he certainly is not riding a sleigh with reindeer in the front. It is more something that helps lift your spirits and the spirits of kids into enjoying this holiday.
Santa Claus is just like the Bible--the stories surrounding the events and personalities are nice, but in the end it is a matter of faith and belief as to what is real or not. Saint Nicholas was a real person who gave gifts to children. Santa Claus is fictitious--the North Pole is uninhabitable and devoid of life. No one can deliver toys in a flying sleigh to every child in a 24-hour period. Kids believe in Santa because it's a magical time of year and there are so many cool stories and movies surrounding Santa Claus. In the end, the jolly old elf is fictitious because the myth doesn't add up to scientific facts.
