Wow, to give up your ancestry and believe the earth is flat and only 5000 years old. To believe in the most abomination of a religions begotten by incest, rape, genocide, whose tenets are to subdue the earth. and fill it with their own kind.
The failure of Hindus is that they are not an organized religion. Further the Hindu education who gave the world mathematics, astronomy the procession equinox does not exist as ancient past. As of now there is no Hindu education. They are religion that worships nature, and get their answer from nature, as science get its answer only from nature.
Further Hindu religion as Hindu time line is in agreement with science timeline, weather it is the age of the universe, or the age of human existence, or even evolution, Like the Nine avatars of Lord Vishnu first, fish, then turtle, then, bore, then midget, then beast(halfman/lion), then human, the memory of Hindus is exact to what science as verified.
Hindu religion whether it is Indra (Dev Raj), of lighting/thunder and cause of rain governs natures, earth, the five elements, is the same Devraj as common electricity as even basic science student will tell electricity govern nature, it govern chemistry, rain, etc. .
Hindu religion is about atma, all have atma, all atmas are equal, through respect of atma one attains god. Therefore better to believe in truth which even in the Gita say to a logician god is truth then believ in things that our disproven.
