Hinduism is the only ancient religious tradition on the Earth which talks about the right time-scale. In the West, people have the sense that what is natural is for the universe to be a few thousand years old, and that billions are numbers no one can understand. The Hindu concept is very clear. Here is a great world culture which has always talked about billions of years.
