That's a pretty simple distinction, but you've asked for us to define abstract concepts without using definitions or abstract concepts. So let's just say, knowledge is what you know and beliefs are what you believe. A belief implies some level of doubt, while knowledge is just the information you have in your head. There is a lot of overlap. I know that the sun will rise tomorrow, because I understand how the earth rotates and orbits the sun. I believe it will happen because I understand physics and observable phenomena. Put it another way, it is a high-confidence belief based on the knowledge obtained through observation and study. Some beliefs are based on nothing more than hope, and some knowledge is beyond any doubt. I believe the Phillies can win the World Series, but I know our bullpen pitches cantaloupes and our hitters are streaky as shit.
I’m confused. You don’t know that the sun will rise tomorrow - you believe it will. Science is our best guess at how the universe around us works. Geocentric was how we believed the universe worked until that theory was proven to be wrong.
You know the current theory, and based on that knowledge you can believe it will rise. There could be some phenomenon that will turn the sun dark for 7 days that is not part of the current model. It’s unlikely, but possible.
Knowledge is the understanding of that which will not change. Yes, you can modify the theory tomorrow but it will not be the same theory as today. That’s why it’s knowable
Anything is "possible". Forecasts of the future can't be 100%. But not everything is plausible. If you round to 100 significant figures, the probability of the sun rising tomorrow is 100%. You'll never get to true 100%, past, present, or future. Even after watching something with your own eyes and watching the video documentation 100 times over. It's "possible" someone faked the video, and eyewitness testimony is known to be incredibly bad evidence for a reason.
Knowledge is strongly backed by evidence. Belief ranges from "the evidence is inconclusive/not strong enough/doesn't exist" to "the evidence can't exist".
