is it true that questions have infinite answers...

Like if we don't know everything,  is it like knowing nothing?  

As with a jigsaw puzzle with out the inifinate peices and even then could that picture be read in many angles and in reverse?

Or how information could for example change everything,  such as if your true parrents were trees would that change your perspective? If so would that mean we are at the mercy of every new layer of information?
