I always like to use this point in service. This is directly from the reasoning book.

(rs p. 181 pars. 2-3 "Holidays" )

"The book The Worship of the Dead points to this origin: "The mythologies of all the ancient nations are interwoven with the events of the Deluge . . . The force of this argument is illustrated by the fact of the observance of a great festival of the dead in commemoration of the event, not only by nations more or less in communication with each other, but by others widely separated, both by the ocean and by centuries of time. This festival is, moreover, held by all on or about the very day on which, according to the Mosaic account, the Deluge took place, viz., the seventeenth day of the second month-the month nearly corresponding with our November." (London, 1904, Colonel J. Garnier, p. 4) Thus these celebrations actually began with an honoring of people whom God had destroyed because of their badness in Noah's day.-Gen. 6:5-7; 7:11.

Such holidays honoring "spirits of the dead" as if they were alive in another realm are contrary to the Bible's description of death as a state of complete unconsciousness.-Eccl. 9:5, 10; Ps. 146:4."

So this holiday has been promoted by the demons through the centuries to comemorate the death of their children, the Nephilim, who Jehovah destroyed. How sick is that?!!!
