That a naive thinking.You didn't try to reason the motivation behind the claims of accused scientists in the article. There have been numerous discoveries of ancient artifacts proving again and again the advancement of our ancestors in the field of science and technology. Why is it wrong to study ancient texts to try to understand their techniques? Why are such professionals are being targeted? Do you atleast believe in ancient medical science of Ayurveda, whose methods are increasingly being accepted in modern medical institutions in Europe and USA? You wouldn't dare point finger at them but you would do it, without thinking twice, when someone from your country try do it.
