Answer 1

Light. It moves to fast. We only see what we see because of light. We built knowledge based on what we see. That knowledge is used to verify or validate what we are seeing with tools, units of measurement, and definitions based on our understanding. We can’t understand what came before the big bang because we cannot see it. The evidence is in the stars and galaxies that are moving away from us and our position way too fast. So fast that the light from them will never reach us and too much time has passed between the big bang and now that our technology might never be able to bridge that gap.
