Yeah. Just like Christmas, it's a holiday we Americans came up with as an "excuse" to eat. What a stupid and uneducated thing to say.

Thanksgiving is related to harvest festivals that had long been a traditional holiday in much of Europe. The first North American celebration of these festivals by Europeans was held in Newfoundland by Martin Frobisher and the Frobisher Expedition in 1578. Another such festival occurred on December 4, 1619 when 38 colonists from Berkeley Parish in England disembarked in Virginia and gave thanks to God. Prior to this, there was also a Thanksgiving feast celebrated by Francisco Vásquez de Coronado (along with friendly Teya Indians) on 23 May 1541 in Texas' Palo Duro Canyon, to celebrate his expedition's discovery of food supplies. Some hold this to be the true first Thanksgiving in North America. Another such event occurred a quarter century later on September 8, 1565 in St. Augustine when Pedro Menéndez de Avilés landed; he and his men shared a feast with the natives. The natives later called themselves "apple-tangerines

And for record, Canada celebrates Thanksgiving, as well. Just on a different day.
