3. Indus valley.

Once, there was a time that Indians were considered to be tribal and suitable to be as slaves. Indus valley excavation and study there proved their judgement wrong. It was after Indus valley excavation in 1922, the vision of entire world turned towards India.

Archaeologists started excavating few old burial grounds in and around Punjab region of Pakistan. It was a surprise for them to find a buried town under the earth in that area. They started their full fledged investigations and found the following results:

1. The people would have lived in that area during 3000 B.C.

2. The layout of the town, usage of burnt bricks and others made the researchersrs to decide that the people  
    lived there were culturally forward on those days.

3. After comparing with other existing ancient sites, they conclude the the people lived there were
    Dravidian.    

4. Archaeologists found many hundreds of 'Siva Lingas', idols of lady Deity (Similar to Durga Devi) and 
    Vishnu. An idol of a man in yoga posture also was found. We can understand from the findings that
    Hinduism was in existence even on those days.    
   
This area was so fertile due to the presence of Sindh river on those days. The people in that area was forced to vacate after few centuries due to water scarcity as the river Sindh changed it's route.

Water is considered to be so sacred even today. It is a general belief that certain rivers or water from the falls can cure diseases. There is a scientific reason behind this belief.

"Gangaicha Yamunai chaiva Godavary Saraswathy Narmadhe sindhu Kavery Jalesmin sannidhim kuru" - This is a Vedic hymn.

We can understand from the above hymn about the importance given to rivers on ancient days. Hydro power projects and Hydro carbon fuels are examples to explain the liquid sources of energy.

Lemuria Dravids driven out from there by the water (Indian ocean's erosion). Indus valley Dravidian were forced to vacate due to scarce of water, in a contrast. It is my wild imagination that the Lemuria Dravids would have occupied the Indus valley after driven out from there during the first erosion of their land.

It is awful to note that the oldest Human sapience' origin was Lemuria Dravidian's (African forest which was a part of Lemuria). The oldest world civilisation also belongs to Dravidian. While all the other world civilisations became extinct, Indus valley Dravidian civilisation alone is still existing.

Digging continues.
