Question: How do we know that we are seeing the same things as eachother?

Good question, your brain may be registering a lot more information through your eyes than mine does. But you are just as limited as me when it comes to your understanding of objects seen around you.

In other words, I believe it is possible for you to see something that I do not (as long as it exists, we’re not on about ghosts here). It just the matter of time until we can figure out how to enhance the unseen to make it visible!
