I often wondered why a civilization so advanced in town planning, drainage system and scripts will just forget it all... But to think of it a 900 year old drought is big enough to make beasts of saints, lest alone ordinary citizens of a civilization... We need to rethink about the plight of our ancestors who abandoned their ancient civilization for the fury of nature and not any 'Aryan' invader .
We need to understand that the people lived in those times were even scientifically so advanced that even today, the scientific community is not able to understand some of the procedures of magnificent construction, using which the ancient people used to cut rocks in large quantities to build temples, etc. In a single rock.
