We haven’t found the edges or the center of the universe yet, and might never. Every time we build a better telescope, we find a few hundred billion more galaxies all racing away from each other.

This finding seems to be based on some assumptions.

In calling these “the first stars” they are assuming that their observations are coming to an end. I mean, what else is there to look at in our past beyond the first?

Are they quite sure these are from the “first stars in the universe”?
Or do they just think these are the first stars in the universe?

Following the big bang, the universe initially existed as a cold, starless expanse of hydrogen gas awash with radiation, known as the Cosmic Microwave Background.

"Follwing the big bang": Big Band is an assumption

"the universe initially existed as a cold": Another big assumption of a "cold universe"

"starless expanse": Yep! Astronomers were there to witness that occurrence, with "no stars" and a "big expanse"

starless expanse of "hydrogen": why hydrogen; what came before the hydrogen?

"awash with radiation": where did the radiation come from? Hydrogen by itself is not radioactive. The big bang? That's assuming that the big bang caused radiation, but radiation has to arise from something that existed before hydrogen, so, all the radiation was created by the big bang?

"Known as the Cosmic Microwave Background": These are just observations of microwave radiation, but, did it actually come FROM the big bang, or did it exist before, or was "something" else responsible?

I hate not having the complete story, but, for now, speculation and theories is mostly what cosmology is about.
