ELI5:How does Santa Claus deliver all the presents in one night?
gpt
He outsources it to parents around the world. About a month or two beforehand, he would have placed these gifts intended for children all over the world at different malls and websites around the world, so it's not like he does it all in one night actually; he has weeks to do it, and as we all know, it only takes 80 days to travel around the world. 

Parents then collect these goods at the shopping establishment of their choice, and donate a fee to Santa for his upkeep of the elves and reindeers. These gifts from Santa are then placed at the Christmas Tree at the family house, and allowed for children to open on Christmas Day itself!
