Does knowledge exist outside of, or separate from, the individual who knows? Constructivists hold that human knowledge, whether the bodies of content in public disciplines (such as mathematics or sociology) or knowledge of the individual learner, is a human construction (Gredler, 2001).

I do not believe that there is knowledge outside of human beings, at least that we know. I believe that knowledge comes from the human being and his capacity for evolution in his years on earth, of course we do not know the whole universe and it is huge, but as far as we can know, this is the truth.

for example develop your sense of humor.
