I ran across the work of Isaac E. Mozeson a few years back. He is a leader in a discipline known as Edenics. He believes in the monogenesis of language. That is that all the languages in the world stem from one mother tongue or the language spoken in Eden. Many scholars are now taking this view of language (monogenesis) seriously after discarding it for a number of years. I wanted to introduce Edenics for two reasons.
1) If everyone on the planet is connected through a common mother language that has been split up and changed over time. Then it is not unreasonable to believe that there is one true religion that has been split off from and changed over time. However, just as it happens in language, religion has been flipped around and turned upside down in many cases.
2) That means at one time everyone agreed on what was right and what was wrong as a group, because language, culture, and life are deeply intertwined. Then we can link our faith to the dawn of humanity of which we can all trace our roots.
So I think you will enjoy this introduction. Check it out:
