How Much Do Human's Know? How Much Do You Personally Know?

Taken as a percentage, what would you propose is the sum of man's knowledge of the known universe?  If I were to break that down a bit, what do we know about all things outside of earth's domain?  Of all the stars, planets, black holes and other things swirling around out there, what do we human's know?  1%?  Less than that?  .1%?  .0000000001%?  What would you suggest?

Closer to home - Of all that there might be to know about the things in the domain of earth above the ground, what % do we know of what there might be to know?  About clouds, whether patterns, things that might live 5 miles above the earth?  1%?  .1%?  .0001%?  What number would you put on that?

Still closer - Of the things that populate the earth's floor, like animals, plants, rocks, bugs, and other things that are neither in the air or under the earth or water, what % do we know?   .0001%?  more?  less?

What about the percent of our knowledge of things under the ground?  Then what percent of thing under the water?  What % of knowledge do we possess of all the things there are to know about human anatomy, especially the brain?  What % do we know about human psychology?  And what % do we know of human interaction with others, including other animals, plants, and our environment?

What % do we know about the microscopic and invisible things of life.  What % of knowledge do we have about the history of man, life, the planet, the universe?

If man's total knowledge of the things of his world and his universe amounts to some miniscule amount compared to all there is to know, then what percent of all human knowledge do you personally possess?  1%.  .01%.  Much less?  And of what you "KNOW" to be true and what gives credence to your unique understanding?  The ideas and opinions of other men who also know as much as you about all of this, but maybe a bit more about something you don't?  And what is the source of their knowledge?

And yet we are ready to fight, draw blood, destroy lives, and kill over our understanding of how things are or how we think they should be.  Personally, as I sit in my home office and stroke my new kitten, I know for sure that I know a very small fraction of the workings, thinkings, and ways to train and take care of this much studied little animal.  We are fools to think we have any real knowledge, and this is the Christian God's definition of pride.
