Do all questions have answers?

I would not say all questions have DEFINITE answers. There are questions to which evidence can be quantitative and measured and gave them proven, relevant answers. There are other questions in which the answer would depend on one's own individual preferences or experiences (there is no accounting for taste, after all, and different people can come out of the same situation, event, or dilemma bearing completely different feelings or reactions). Then there are those who have never for sure been proven by science or by individual experience. I guess "Is there a God?" and "What is the purpose of life? Why are we here?" would be examples of those. Some have had experiences that they claim have led them to definite answers, however, it is not something those people would be able to successfully prove to someone who had not had the same experiences. And those we do have scientific evidence and historical evidence here and there, no one has the final piece of the puzzle and there are many, many differing theories as to where it all comes from and where it leads to. So do all questions have answers? Absolutely, but not all questions have KNOWN answers or answers that are fully understood by all.

Some have different angles to answers but not just ONE that is correct.

i agree with you that all questions have answers, though some answers are difficult to find or search. some question takes weeks or months or sometimes years before we find out the answer. but as i was replying here i remember when my children are toodlers they ask questions that are so hard to answer.... lol.

All questions have answers but answers may be different from each other. We know the answers or we have answers but still we like to question because we like to know others answers, others views on that questions.

I believe every question has its own answer, the only thing is that we have to find out the answers for these questions.
