Hey,
An architect is a person who plans, designs, and reviews the construction of buildings . To practice architecture means to provide services in connection with the design of buildings and the space within the site surrounding the buildings

Archaeologists study human prehistory and history , from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology as a field is distinct from the discipline of paleontology , the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for whom there may be no written records to study
