It’s because we are three dimensional beings in a multidimensional universe. It would be like a 2D being trying to understand a 3D world. Things would blink in and out seemingly at random.

I'm not a physicist, but I'm pretty sure there are only three spacial dimensions. We can talk about time as another dimension, and I don't know enough to say there aren't other dimensions like that, but I'm pretty sure there are only three spacial dimensions.

I don’t pretend to understand it but string theory is one prominent scientific theory which suggests there are a lot more than 3 spatial dimensions.
