Amen (Hebrew אָמֵן, Greek ἀμήν, Arabic آمِينَ, Amharic አሜን) is, according to Wikipedia, “a declaration of affirmation first found in the Hebrew Bible and subsequently in the New Testament. It is used in Jewish, Christian and Muslim worship as a concluding word or response to prayers.”
But the roots of the word may be found in Africa and the cosmology principally of ancient Egypt
From NYANKOPON and NYANKONTON - RA and RAIT - By Odwirafo Kwesi Ra Nehem Ptah Akhan
Africans have always understood that the Great Mother and Great Father function together as One Divine Unit – the Supreme Being.
The most ancient name for the Great Mother and Great Father is Amenet and Amen as shown in ancient Khanit (Nubia) and Kamit (Egypt). Amenet and Amen are called Nyamewaa and Nyame in Akan culture.
It is Amenet-Amen as the Great Being who direct Ra and Rait, the Creator and Creatress to create the Universe. This reality is one that African people can and have verified via their direct interaction with Amenet, Amen, Ra and Rait over tens of thousands of years. This reality is thus woven into the fabric of their cultural and religious expressions inclusive of the manner in which they articulate cosmology. This was true in ancient Khanit and Kamit and is true in Akan culture – in its authentic expression.
This publication also serves to correct the misinformation put forward by egyptologists who fraudulently attempt to conflate Ra, Amen, Atem and Khepri into ‘aspects’ of the ‘one god’. In reality, these are Divinities in their own right with clearly delineated roles in Creation.
