"Using the James Webb Space Telescope, astronomers have spotted a massive and densely packed galaxy cluster at "cosmic noon." The fact that this cluster is so highly evolved could change theories of cosmic evolution, as it seems to exist before such structures were thought to be possible.
Designated XLSSC 122 it resembled the galactic clusters found much closer to our own galaxy.
*However, this cluster is seen as it was around 10.4 billion years, just
around 3.4 billion years after the Big Bang, a time when such structures were theorized to have only just begun to assemble.
Light normally travels in a straight line, but spacetime is the track that it follows. If spacetime is curved, then the path of light is also curved. The closer that light travels to an object of great mass, the more its path swerves.
That means when an object of great mass, in this case XLSSC 122, comes between Earth and a more distant light source, light from that background source arrives at our telescopes at different times based on the path it took around the intermediate object."

--EASY ANSWER: It seems to exist before such structures could is because, well, it is not that old and was CREATED as is. Your timeline is WRONG.
