I'm probably oversimplifying, but I'd imagine they all just think Coop didn't actually do anything. From their perspective, he went through a black hole, disappeared, and showed up again. That's wild, but not heroic. They all think Murph is a genius but a bit disturbed. Nobody, even her family, believes that she got her theory from her father. They credit her as a genius and think she had her math in her head even if she didn't realize it. That makes Coop interesting and Murph the savior of humanity.
I will quote another poster from an earlier comment.
- The space station is named after Cooper's daughter, and according to the doctor tending to Coop, "She's always maintained just how important you were" (referring to Coop).
- Cooper's handler/chauffeur on Cooper Station tells Coop that he wrote a high school paper about him. "I know all about your life back on Earth," he tells him.
- And as someone mentioned earlier, they recreate Cooper's and Murphy's home on Earth on Cooper Station.
In other words, there's no way everyone and their dog doesn't know about Coop's exploits, and what he did to save the world. That he's still alive, all those years later, should be even more of a shocker.
