In Halo Infinite we back on reach

In Halo reach you will return to Reach?
It sounds absurd as a hypothesis, but it could be plausible. As we were told by “cortana” that his plan had been designed since its first contact with dominoes and precursor technology. We know that the first contact took place in halo ce in the control room, but what if that had not been the first contact with a precursor technology?. In fact if we think about it Cortana may have had contact with such technology on reach. In the exodus mission we can see on the site a huge “alien” artifact, which the professor has studied in depth with the help of cortana. If you enter the tribute room we can see that the core of the artifact is connected to the lab is most likely also cortana. It is no coincidence that the importance of cortana and studies are defined as “vital” by the doctor, in fact such studies will save humanity.
Finally there is a second element that leads us to think about a return on reach. At the end of the game we can see the state of the planet after several years of vitrification, to the left of the clearing we can notice a seemingly human ship. Is this an actual return already thought by Bungie or is it just the return of humans to the planet after the war?
What do you think?
Would you like to return to reach in Halo Infinte? Could this theory be true?
