The Rosicrucian Order, I think this order is much older...
For beginnings of Rosicrucianism are considered to be the Egyptian mystery schools, which were made available to the public by Thutmose III (1486 - 4 March 1425 BC)??.
The Rosicrucian Order as a secret brotherhood dates back to AD 46. It was created by the fusion of the "magical" traditions of Ancient Egypt and !Christian teachings?! The Alexandrian Orm is also mentioned in this context. This is why the Library of Alexandria was secretly looted, moved and then set on fire so that no one would look for the books, scrolls and tablets.
I know there is some connection between the Rosicrucians, Templar Order, the Brotherhood of the Serpent, the Babylonian Brotherhood . All have their origins in ancient Egypt.

High-ranking priestesses had a snake tattooed on the front of their left shoulder, and after their death a strip of tattooed skin was cut out and kept. They were initiated at the age of 12, if they pass the tests..

The ancient Greeks and Romans believed that books on magic were invented by the Persians. The 1st-century AD writer Pliny the Elder stated that magic had been first discovered by the ancient philosopher Zoroaster around the year 647 BC but that it was only written down in the 5th century BC by the magician Osthanes.
Egyptians commonly employed magical incantations, which have been found inscribed on amulets and other items. Woodoo also has its origins in Africa.
The Egyptian magical system, known as heka, was greatly altered and expanded after the Macedonians, led by Alexander the Great, invaded Egypt in 332 BC. Coptic writing system evolved, and the Library of Alexandria was opened

All churches and the religion practice use the teachings of ancient Egypt to control the masses of people.

My question is? Where did these ancient sciences come from in Egypt?

Everything is connected to everything.

HEKA is identical with the Egyptian ḥkꜣ(w) "magic" in Coptic:ϩⲓⲕ hik.This hieroglyphic spelling includes the symbol for the word ka (kꜣ), the ancient Egyptian concept of the vital force. Weret Hekau is Great Lady of magic.The Old Kingdom Pyramid Texts depict Heka as a supernatural energy that the gods possess.

❗"Cannibal pharaoh" ❗ must devour other gods to gain this magical power (only the one with specific (divine) DNA the pure human being, can use it.) - this is where the cult of cannibalism and vampires comes from.

"Heka have been created at the beginning of time by the creator."

Heka magic is many things, but, above all, it has a close association with speech and the power of the word. Actions did not necessarily speak louder than words-they were often one and the same thing. Thought, act, image, and will are theoretically united in the concept action of Heka.
