I'm talking about vedas and not upanishads. Please go and read my comment again. Upanishads are derivatives of vedas.
And here's good for thought for you since you're open minded:
Find the oldest "confirmed" Hindu idol and compare it with the age of Hinduism! :)
Upanishads are considered as Vedanta that is the essence of Vedas, you sure need to do a lot of learning before lecturing others
