It has been a very gigantic research question in the human history to find out what exactly was the language God spoke to Adam and Eve in the paradise. Many languages such as Hebrew, Greek, Latin, Sanskrit, Arab, Welsh, Finnish, French and others were claimed over ages that they were the languages spoken by God and Adam. They only left the world in chaos of shallow knowledge on the origin of language and the first language spoke on the earth planet. In this masterpiece called Theophilology, we have put our discovery of this language, its name and how it was applied in the past and even in this present day. The oldest language is having similar syntax with the modern languages but the morphology, semantics and its phonology sometimes are evolving.
