It looks like your question is incomplete or unclear. Could you please clarify what you mean by "how many years ago was 9"? For example, are you asking:
- How many years ago was the year 9 AD?
- How many years ago was 9 years ago from today?
- Something else related to the number 9 and years?
If you mean how many years ago was the year 9 AD from the current year 2025, the answer would be: 2025 - 9 = 2016 years ago. Please let me know if this is what you meant or provide more details!
