Q: Why didn’t the aliens on the UFO land on Christmas morning?
A: They were selfish, and did not want to share their presence!

Explanation: UFOs are unidentified flying objects, often seen as flying saucers.  Flying saucers (if they exist) come from other galaxies and may have alien life on board.  Wouldn’t it be fun to have proof of life from other parts of the universe!  While there are many stories and pictures of UFOs, the existence of space aliens has never been proven… yet.  They have never made their presence known to us.

Many people in the world celebrate Christmas on December 25.  One of the most common Christmas traditions is to give gifts to friends and family members. Gifts are also called presents.  Some people like to share their presents, while others do not want to share.

This joke is funny because presents (the gifts we give and receive) sounds just like the word presence (being in a place).  The presence of life from other planets would be a present for people who hope for extraterrestrial life.

The James Webb Telescope that was launched yesterday may give us many presents as it helps discover more about the universe.
