Dear balaord, You are right that there are not much evidences. However, you must know the basic difference between christians and Hindus (and perhaps muslims) is their quality of documentation. Christians are extremely good in documentation. All our ancient knowledges have been lost just because of our lack of documentation. You can realize the difference instantly if you happen to meet any american or eurpoean and transact any business. They will document the entire meeting. It is in their culture. This documentation ability of christians basically conveys the feeling that their science is superior to us. Have you forgotton all those geographical indications (WTO)controversies about neem, haldi etc.? Our forefathers have made the mistake of not recording their knowledges and that's why we are not in a position to convince the person like you with evidences. At least we should wake up and start recording our ancient wealth of knowledge.
