1) Around 2020 years ago, God sent his son Jesus to live among humans to show them how to love one another and God, as people at the time did not love as God hoped. 2) God told Mary she would give birth to Jesus, and an angel told Joseph in a dream to not call off his engagement to Mary and name the baby Jesus. 3) Mary and Joseph traveled to Bethlehem for a census and Jesus was born in a stable, as all other places were full, and was visited by shepherds and Three Wise Men who brought gifts.
