What Knowledge is...?

While thinking on the word or the concept called ‘Knowledge’, i.e. 

what knowledge is...?

Or to what one should call the knowledge....?

Is it a Philosophy...?

Is it Spirituality...?

Is it a Science...?

Is it any –logy...? Or anything else

Then after pondering for a short time, I realized...

“Knowledge is when our thought eagerly travels a path of positivity for urge of knowing surrounded with belief.”

Then I imagined the period of very inception Human Kind. When humans i.e. a species with no cloths and with bent body cum tail were struggling for existence and the story of human evolution went on...

My point is how the very first Book, so far in the human history had been written? I mean how the words containing thoughts have been embedded on the sheet of paper..?

It could have been written or embedded by the means of Positivity and Belief only.. Yes Positivity and Belief.

So, Knowledge is mostly based on positivity and Belief (with the help of experience). Then, whatever is the stream.
