xkcd

My read on it could be very wrong:

I tend to think of it in the context that our ability to directly observe anything at that scale is limited, so while we can record and observe effects, our knowledge of the processes that lead to them is sparser. It’s like having a low-resolution image of someone’s face— you can tell what it is, but without a clearer picture, you have a harder time with the who.

The how of things exists, we just lack the ability to see it yet(unless, of course, the universe is exactly that strange)
