Extinct vs Distinct

Question posed at dinner tonight:
D - "Why are Heavenly Father and Jesus extinct?"
All the older kids puzzling over that and then finally, "They're not extinct."
D - "Then why does it say, 'I saw two extinct personages hovering above my head."
Laughing ensued and we explained the word she was thinking of was distinct and not extinct.
Word confusion!
Glad that's cleared up.
