Fascinating Vinayaka found in Vietnam!

Many readers would have read the India Divine article on 4000 years of antiquated items of Vishnu worship unearthed in Vietnam. It can be  read here:http://www.indiadivine.org/news/history-and-culture/4000-year-old-vishnu-statue-discovered-in-vietnam-r766

While looking for more details on this topic in the internet, I came across unique images of Hindu deities from Oc Eo, in Vietnam. (http://en.wikipedia.org/wiki/%C3%93c_Eo)

What looks like Vinayaka with the trunk is seen as a twin image as below.

What looks like Durga has ten pairs of hands as follows:

Yet another similar figure has a 3- layered crown of 3 Devis. Reminds me of the line "Nava Durgam Maha Kalim Brahma Vishnu Shivathmikaam" of Lakshmi Stotram.

Similar type of multi-handedness is shown for Buddha (presumably) or a king?

See here:

The most fascinating of all is the statue of Buddha in Bhumi Sparsa Mudra.

This is same as the one found in Harappa belonging to a period of 5000 years before present.

 see below.

What better proof can be there for a continuing culture of Hinduism covering greater part of east Asia? The Oc Eo culture was supposed to have existed 2000 years ago.

The Harappan image shows the existence of many Buddhas in Hindu culture as far as 5000 years ago.

This shows that Ikshvahus existed even before that, i.e., before Indus- Saraswathi culture.
