Space in the physical explenation is just a handy framework to work with, which can be modelized in difficult equations, to explain the way matter moves. But if we intermix physics interpretations of time and space to our daily life, worldly interpretation of things, things just blurr out and make no sense. I think that is where the difficulty resides.
The way physics describes and defines things, just don't correspond with the way we humans understand the world to be.

I'm afraid this just isn't the case. The world works in the way physics describes it by definition. If it didn't, we'd have to explain why it didn't. Right now GR, for example, is consistent for anything we can measure the effect of GR to be. That means our theory is complete as of today. Tomorrow we may find an observation that runs against GR, but that's for the future to worry about and we can only offer idle speculation.
The way physics describes things is EXACTLY the way we perceive the world to be. This is often the exercise that is done when first introducing a more complex theory to students. It is often asked that the student prove that the world we perceive
necessarily follows from the complicated mathematical models.
