Should questions that require omnipotent knowledge to truly answer be ignored, and the lack of answers be the de facto answer?
For example, the question "Is there life on Mars?" You can only answer "Yes" if indeed there is life on Mars. If there truly is no life on Mars, nobody is qualified to say that with absolute certainty, as nobody has scoured every inch of the surface looking for it. We can only answer with things like "Nobody has found any yet."
