"Zero" was invented by Indian Yogis without which modern computer is impossible. Their mathematical prefix system is far more advanced than today's math; 10^149 has a special prefix in Vedic math. Modern math only has prefix up to 10^30. Sanskrit language itself is so scientific that it is created in such a way that speaking it everyday promotes good health. All the palatal consonants are placed in one row, all labial consonants are placed in one row, all the dental consonants are placed in one row and so on. It is extremely scientific. During Vedic period, they never invaded any country, nor they looted any country economically and culturally. The only religion with interfaith harmony is found in Vedas and not in other religion. Vedic people never went on preaching their religion like Christian missionaries because they never had any motivation for doing that. Yoga and meditation technique were created by Vedic people to bring higher states of consciousness because they understood that evolution has two aspects: physical evolution and mental evolution. Darwin only talks about physical evolution. The idea of gravitation, sound, electricity, magnetism, electro-magnetic field was all known to Vedic yogis which was later re-discovered by western scientist. All the lofty ideas are present in Vedic literature. They even went further by saying Vedas are merely sounds; therefore, move beyond Vedas!
