What is a silly question?

Is there any question that is silly ? I cant immediately think of any.

Answers can be silly, one can easily imagine such a thing. An answer can be silly for various reasons. There are un-educated answers, so they may be laughable. But are un-educated questions laughable?

An example of a laughable question is ; if there is no God then who wrote the bible? The laughable part is not the question about who wrote the bible rather it is the assumption that nobody except god can write it.

Any pure question considered isolately can't be considered silly or laughable. A question can surely produce laugh given certain setting.Though question can produce laughter without context like the one mentioned before but it is not the question itself that produce laughter that's why I have distinguished it by the adjective "pure". Pure questions may have or may not have any answer. Now lets see, there are some questions that are genuinely bad because they are vague and inaccurate. One scenario is when the questioner fails to form the question properly and question asked doesn't reflect the original question formed in his mind. These are the fault of the questioner as opposed to the question itself. My proposition is a clearly formed pure question can't be silly. A vague question that doesn't even ask anything is not a question at all.

What is the sum of 1+1 ? Is it silly even if asked by a Math PHD? No way!

What is the smell of a circle? Crazy but not silly.

As long as the question doesn't show any pretention of knowledge, how it can be laughable as it doesn't give anything rather ask? And it can't be stupid or dumb for the same reason.

The mastery of certain logic that enable us to see the connection between different statements immediately is far from so for those who are deprived of them. What is natural for a person with the privilege of proper education is not natural (sometime even unconceivable) for those who lack it. All these illustrate the power and neccesity of education.
