How about gifting your dad a book written by indigenous authors that focuses on indigenous practices and knowledge? You could consider "Braiding Sweetgrass" by Robin Wall Kimmerer or "The Mishomis Book: The Voice of the Ojibway" by Edward Benton-Banai. Alternatively, you could gift him a piece of indigenous art or a handcrafted item made by an indigenous artist to support their work and celebrate their culture. Another idea could be purchasing a subscription to an Indigenous publication or supporting Indigenous businesses.
Or you can get him a star map with the date when he welcomed you in this world.
