That honestly doesn’t sound like a dumb question to me. People don’t just get randomly born abroad for no reason, it’s typically because their families were doing something there.
It kind of is though, because Algeria was a part of France until 1962, and there are millions of people of Algerian descent who have French citizenship.
Potentially. But, families can also travel to places where they don't live. They can also engage in activities that are of interest to customs officials, regardless of their residency status.
Rather than guessing, it's prudent to simply ask the question, no?
Its pretty stupid having to explain that to a 50 year old.
