Eli5 How can we see the beginning of the universe

202 views

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?

Ok so the link itself cannot be an explanation even though it does a better job than I ever would. Basically the further away something is the longer ago the light coming from it originates. So by looking extremely far away scientists noticed that galaxies and such got more simple, like they were newer in their formation. Once they could look what the equivalent of some 400 billion years ago is in light speed, they stopped seeing things entirely.
