The Kingdom of Ta-Seti is the oldest Nile Valley Civilization that existed first before Kemet.
For this reason, the Nubian people of the Kingdom of Ta-Seti are regarded as the Founders of Kemet. As a result, Ta-Seti and Kemet are both considered to be the original names of Ancient Egypt.
Ta-Seti was known as The Land Of The Bow which was the main weapon of the Nubians of Ta-Seti who established the first Egyptian Kemetic Civilization.
Ta-Seti is considered the oldest Nile Valley Civilization because by at least 3 800 BC, Ta-Seti had risen to become the most powerful Chieftancy in the Nile Valley region during the Unified late Naqada Period of Egyptian History.
Egyptian artefacts such as the Narmer Palette suggest that by the time Egypt was unified by Narmer, the Kushite Nubians of Ta-Seti had already founded their own Nubian Dynasty which was clearly older than that of Ancient Egypt which suggests that Ta-Seti is the oldest Nile Valley Civilization.
It is possible that the origins of the Ta-Seti Culture can be found in the Anu people who may have been the first group of people to settle the Nile Valley based on the Terra Neta Tile found at the Temple of Abydos.
The Qustul Tombs near the Sudanese border show various symbols of Ta-Seti Royalty which also show that Ta- Seti is the oldest Nile Valley Civilization.
These Nubian Kushite artefacts such as an incense burner, a Palace facade, and a King wearing the Southern Nubian Kushite Crown sitting on a Throne in a boat bearing the Royal standard of the Falcon God Horus suggest that since a unified Nubian Monarchy was already established at Ta-Seti by 3 800 BC, Ta Seti is the oldest Nile Valley Civilization and it provided the Template for Egyptian Kingship once Upper and Lower Egypt were later united under Narmer’s Dynasty.
Evidence of the Ta-Seti Kingship in Ancient Nubia from the Qustul Tombs and Narmer Palette means Ta-Seti predates Ancient Egypt.
Ta-Seti is thus the oldest Nile Valley Civilization because Ta-Seti provided a Prototype Dynastic Model of Kingship whose symbols were later adopted by Ancient Egypt (Kemet).
For this reason, Ta-Seti is considered the oldest Nile Valley Civilization which existed before Egypt (Kemet).
Conclusion
Based on the Narmer Palette and Archaeological excavations at sites like Qustul, there is evidence to conclude that Ta-Seti is the oldest oldest Nile Valley Civilization which existed before Ancient Egypt where a unified Nubian Monarchy ruled from the Southern Province of Ta-Seti from at least 3 800 BC.
This earlier Ta Seti Nubian Nile Valley Culture existed into the late Naqada period of Egyptian History, and extended from the South downwards along the Nile as various new Provinces or Nomes were created until the Unification of the South (Upper Egypt) and The North (Lower Egypt) by Narmer.
As the oldest Nile Valley Civilization, the Ta-Seti Civilization should also be regarded as one of Pre-Colonial Africa’s greatest contributions to world Civilization. 
Today Historians also recognise Ta-Seti as the first Nome (Province) of Ancient Egypt thereby acknowledging the existence of Ta-Seti as the oldest Nile Valley Civilization which founded Kemet.
As stared above, it is for these reasons, Ta-Seti and Kemet are both considered to be the original names of Ancient Egypt.
