Hello, I am an archaeologist, I recover and analyze material culture. 
Good, a person who studies human history and prehistory through the excavation of sites
Yep, I studied it as a social science and a branch of the humanities back in college. 
Ok good. from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. 
It is really different from the field of paleontology, which is the study of fossil remains, but people still get confused between the two!
Oh oh.Archaeology has various goals, which range from understanding culture history to reconstructing past lifeways to documenting and explaining changes in human societies through time
I agree, I love learning about prehistoric societies, I was part of one at my previous job.
