Much of Asia ?? Hallo, I believe most of the Asian population is made up of China and India.
Hinduism, for one, has no problem with evolution. In fact, evolution nicely fits in with the theory of reincarnation and the evolution of a soul over many lifetimes into higher and higher life-forms. As for young-earthism, Hindu belief includes astronomical time scales in which the Universe is born and destroyed... this is not the first Universe created by the Creator, not will it be the last.
This is not an endorsement of Hinduism, which includes such delightful things like casteism, unequality of women and other social evils. All I'm saying is, there is no conflict between orthodox Hinduism and Evolution and the true age of the Earth.
As for China, I believe a signifcant part of their population is Buddhist.. which again, has no problems with evolution because their basic tenets speak of the evolution of a soul over many lifetimes. Perhaps somebody could shed light on what Taoism and Confucianism has to say on this matter.
