I think Mr. Rafi has a point. Its the message, not its geometrical shape.
World is big, not every one is at same level, not every one speak same language, different minds absorb differently. Books of Scriptures have most common messages and they are simple. All Human are born with the message, of whatever religion or believe. Even communist or atheist know, whats evil and whats good, good and bad values remain same. So message is important.
Three major scriptures are of Abrahamic origin. They were given by real people, called messengers. They aimed to improve things, character, economics, social behaviors, laws in their constituencies in their time. As the world is growing rapidly, demands are changing, people are more analyzing and want to understand the real right path, not just translations. This is good, for religion can help us orient our life. I believe religion is part of human DNA.
