Hello
@GandalfTheWhite, for what it’s worth, I believe the point that the GotQuestions.org article/video holds as most important is the fact that Jesus WAS born, and that the day He was born on is inconsequential (which is good, since no one truly knows what day it was anyway).
His birth is certainly worth celebrating (whichever day of the year it actually falls on), though I believe it’s nice to have a day* to point to, particularly for those who do not know Him!
*(His birth, as the article points out, is actually worth celebrating EVERY day, and I agree and also believe that it is, collectively anyway, by those of us who truly know Him)

p.s. - I look forward to watching the video you posted for us. Thanks!
