Eh not completely true as there is a thing called “history” we all have to/had to learn and is kinda important and archeologists play a major role in there . So its not only for people who like museums . Also biologists also make use of the works of archeologists for basing some things about evolution, earlier species, geologists also use the works of archaeologists etc . And that’s just from the top of my head and there could be and I’m pretty sure there are a lot of other important things that are held up by the work of archeologists .
