Puzzling thing about Speed of Light/Speed of Causality

I think the biggest indicator that we aren't living in a simulation is the fact that the further away we look, or at the smaller scle, we find more detail. Progress in science is limited by our ability to measure. If we were living in a simulation then it has worked consistently since we were small mammals staring up at a night sky with stars, to creating the first telescopes and determining that some stars were planets, to determining that some were galaxies, sticking a telescope in space and finding yet more galaxies in what looked like an empty region of space, to measuring the rate of expansion of the universe and mapping the background cosmic radiation. Add to that other ways of measuring the cosmos with radio interferometry and measuring the flexing of spacetime itself. On the other end we've created microcopes, digital cameras that can read single photons, microscopes that can use X-rays, magnetic fields, electrons to particle accelerators to probe at a sub-atomic level. And from one end of the scale to the other it has led to a consistent level of reality.
