How to reconstruct past

Archaeologists reconstruct the past in the following manners:
(i) They excavate the ancient sites related with culture or civilisation. They find out remains from the site such as seal, material remains of houses, buildings, pots, ornaments, tools, coins, weights, measurements and toys etc.
(ii) Sometimes they find skull a, tones, teeth, jaws, and some articles kept with the bodies. Archaeologists take help of botanists, who are specialists in ancient plant remains. They also study the animal bones found at different sites with the help of zoologist.
(iii) Archaeologists try to identify the tools and implements used for cultivation and harvesting. They try to find out traces of means of irrigation such as wells, canals, tanks etc.
(iv) They used present day analogies to try and understand what ancient artefact were used for. Sometimes they compare the ancient findings with present day articles.
(v) Archaeologists observe the different layers of sites and try to find out different things which give pictures of socio-economic conditions, religions and cultural life of the past people in different times.
(vi) In order to identify centres of craft production, archaeologists usually look for the following: raw material such as stone needles, shells, copper ore; tools; unfinished objects; rejects and waste material. In fact, waste is one of the best indicators of craft work. For instance, if shell or stone is cut to make objects, then pieces of these materials will be discarded as waste at the place of production.
