the Egyptians were apparently practicing circumcision at least a thousand years BEFORE the bible began to be written.

Considering the impressive length of pharaonic history and the practically countless inscribed monuments, circumcision is not well represented historically in ancient Egypt. There are only two monuments which specifically depict the act of circumcision: in the tomb of Ankhmahor at Saqqara and in the temple precinct of Mut at Karnak (Filer 1995: 90). Other monuments such as Uha’s mention circumcision but do not depict it. Circumcision is not mentioned in the extant medical papyri (ibid).

The depiction in Ankhmahor’s tomb is worth reviewing. Dating to Dynasty 6 and specifically to the reign of King Teti (2355-2343 BCE), it is the oldest extant depiction of the act of circumcision from ancient Egypt. Here is a line-art version of the depiction, which appears on the east thickness of a doorway in the tomb:

...Ankhmahor was a high-ranking official whose tomb was small but beautifully decorated with relief carvings. It is found in the pyramid complex of Teti. His titles included overseer of all the king’s works, overseer of the two treasuries, priest of Maat, and lector priest (Kanawati, N. & A. Hassan 1997: 11-12).

The above scene depicts two men being circumcised. The scene has been interpreted in different ways but the nude male at right is surmounted by an inscription in which he says: sin wnnt r mnx (“Sever, indeed, thoroughly”). The man kneeling before him says: iw(.i) r irt r nDm (“I will proceed carefully”).

Keep in mind that the bible is in reality only around 3,000 years old - at the earliest, dates back to 1,000 BC. So the Egyptians were apparently practicing circumcision at least a thousand years BEFORE the bible began to be written.
