I know nothing about people whose life is not mentioned in books, while I only have superficial knowledge of people whose life has been recorded in literature.
I have only superficial knowledge of astronomy, with no knowledge at all of trillions of other planets and stars.
I have no idea of how it would be to be able to perceive the full electromagnetic spectrum with all the all wavelengths (visible light, infrared, ultraviolet, radio waves, X-rays, microwaves, gamma rays and cosmic rays) at the same time. I don’t know how I would not be lost with all that information.
I don’t know how to build a combustion engine, a computer or even a TV set from scratch.
I know nothing about the exact way my own body use DNA in conjunction with my cells to keep me alive and functioning.
I know nothing of the millions of species that became extinct without leaving a fossil and have only very superficial knowledge of the ones who left a fossilized presence.
I have no idea how elementary particles such as lepton, muons and bosons can be so amazingly small and far apart, yet create the building blocks of atoms, which in turn create our physical environment.
I have no idea how memories and data are stored in my own brain or how my neurons use chemical reactions to access and organize data to form a coherent pattern that is the article I’m writing.
