Indeed. Ancient Indians were quite innovative. Mohenjodaro had an excellent system of water distribution and sewerage thousands of years ago. Something lacking in many parts of modern day India and Pakistan.
Speaking of proud heritage though, I have to mention
another famous Indian I came across recently. although she wasnt ancient, her story I found extremely inspirational… Anandi Gopal Joshi was the first Indian woman to receive a western medical degree and was also believed to be the First Indian woman to set foot on Amercan soil… very impressive story, and also tragic as she died very young.
