The Vedic hymns record the name of an enemy people who lived on the Russian steppe in the age before the Vedic speakers migrated and, eventually, descended on India in their primitive chariots. The enemy people were called danawo, and they may have been the Proto-Greek danawoi', who became first Homer's Danaan Greeks (who were the people who actually brought the Greek language to Greece and fought beneath the walls of Troy), and then the Danuna whose likenesses the Egyptians recorded on their monumental friezes celebrating Egypt's existential victories over the Sea Peoples under Merenptah and Ramesses III; and finally, after they settled in the Levant under Egyptian pacification and proselytized to the Jews and their religion, the Biblical Tribe of Dan.
No people has ever had such an amazingly long career arc through the great and sacred literature and monuments of antiquity, and no fewer than four great civilizations.
This has nothing to do with the tribe of Dan. You are retconning a single word, ignoring its actual history.
