I'm from belgium. Annyway I like the sorta quistions who're easly ubtainable and are open for some debate unlike some philosphers who would argue and turn quistions around until the mean nothing and make there novels strangly resemble a better form of who dun it detectives.
Asking why is there anything? or what is nothing? - is the same as asking about the existence of the universe. This, I agree, if a top contender. However, as it may have an answer, wouldn't a question with no real answer be more philosophical, such as what is the meaning of life?
You should already know the anser to that if your a christian, the more vague the question the more philisophical (in my opinion)
