Ever hear of archaeologists, geologists, and astronomers?
In fact, I am an archaeologist. And I guarantee you that we can indeed observe the past.
“And I guarantee you that we can indeed observe the past.”
Incorrect statement. Archaeologists can observe the fossil record of plants and animals that lived in the past.
Hey, what ever happened with the walls of Jerico? Any body ever dug up those crumbled things?
No, you cannot. You can observe the relics and artifacts left from the past and make deductions and guesses.
Archaeologists engage in historical research,not scientific research. They look for evidence about the past and base conclusions on that evidence. Scientific knowledge may aid in that research such as by helping determine diets and diseases of people in the past. But the study of the past is not a science.
Geology is a science when it examines such matters as determining what geological formations might indicate locations where petroleum could be found. Determining how those formations developed involves historical research.
