Foolish people react like U, Do you think that human race is only 2-3000 years old? If not than only those people are intelligent who were born between 1800- 2000AD? Dear Kan It is reoccuring phenomenon. People in Rama or Krishna time not only had aeroplanes but remote control missiles and anti missiles, atom bombs, mobile phones, satellites and some other gadgets which you will get in next 20-40 years. After that human race will again start from development from scratch. From your modern science also your fore fathers were monkeys and I am sure they could make bridges.
