I get that light takes time to travel and that we can look at far out stars and galaxies and understand that they’re thousands or millions of light years away.
But we can only perceive light that’s been coming towards us. How can we see the beginning of the universe if we were in the universe? It’s not like we moved faster than light and billions of years later we looked back to see the events happen.
Wouldn’t that old light have gotten to our spacial position way sooner than we physically got here?

The big bang didn’t happen in a specific place, it happened everywhere all at once. So it’s not like light from some event in a specific place happened and now it’s passed us by. Every second, we’re just seeing the light from the part of the universe that was 1 second further away because it happened *everywhere.*
