Please correct me if I’m wrong in understanding big bang, I understood that there was nothing in the beginning and everything was formed all at once, hence the light from the farthest will take billions of years to reach us to see it’s present moment and so why is matter limited, honestly feels like a computer simulation since everything is limited in nature.

Because the universe is expanding.
The universe expands VERY slowly – it doubles in size every 10 000 000 000 (10 billion) years. This doesn’t seem like much, but it does mean that if light starts far enough away, it will never get to us. Specifically, if light starts more than 46.5 billion light years away from you, the universe between you and the light is expanding as fast as the light is getting closer – and so will never reach you.
