You didn’t ask the same question both times. In order to be definitive and conclusive you would have needed ask both the questions with the exact same wording. In the first prompt you ask about a number of deaths after a specific date in a country. Gaza is a place, not the name of a conflict. In the second prompt you simply asked if there had been any deaths in the start of the conflict; Giving the name of the conflict this time. I am not defending the AI’s response here I am just pointing out what I see as some important context.
