Knowledge can be anything such as religion or belief this is knowledge because it is what people have thought for millions of years and what people keep thinking this creates a sense that that is correct. My expedition for example is Cristo rei in Lisbon Portugal this has been up since 1959 which is most of our lifetimes this gives people like a reason to believe as why would someone build a statue so large and so time consuming if it had no deeper meaning?
I think this statue was built as a sacrifice of time and resources to show how they want to represent their religion.
Knowledge can also be opinion which what everyone believes this could be caused by not being educate or just never being exposed to things like how some kid which have been surrounded by war ever since they were born then they might not know a world where bombs and gunshots are going of everywhere.
Knowledge can also be facts and be proven by science this include things like how coronavirus is a virus this is proven after extensive testing on characteristic and how the cell is made which many years back couldn’t of been proven this can mean that technology advancing has allowed us to use stuff light x rays and microscopes to see things we would of never seen like little bone fractures or how large a bacteria is very accurately all due to advances it technology which have proven ideas or theories but also have falsified theories and ideas which made new thing been proven.
Knowledge can also be experiences like how maybe one day you saw a squirrel for the first time, and it was a red squirrel so until you found out that there where many types of squirrels whenever someone asked what colour was a squirrel that person that has only ever seen a red squirrel then they will get the image that the squirrel is red and replay with the wrong answer.
