I hope you know what Pessach celebrates and that it has something to do with the Bible?? Besides the movie 'The Mumie' is a bit older than Matrix

But well if you think that Egypt has only Mumies and completly neglect the rest i can't help you.
Only about the age. Egypt was unified and under a pharao around 2950 BC Sumer was founded at 2800 BC so much to your predating.
About other achievments here an excerpt from wikipedia:
The earliest evidence (circa 1600 BC) of traditional empiricism is credited to Egypt, as evidenced by the Edwin Smith and Ebers papyri. The roots of the Scientific method may be traced back to the ancient Egyptians. The ancient Egyptians are also credited with devising the world's earliest known alphabet, decimal system and complex mathematical formularizations, in the form of the Moscow and Rhind Mathematical Papyri. An awareness of the Golden ratio seems to be reflected in many constructions, such as the Egyptian pyramids.
They were the first to produce glass developed the first known paper(papyrus) and had high knowledge about the human body.
from the timeline of mathematics:
ca. 3100 BC - Egypt, earliest known decimal system allows indefinite counting by way of introducing new symbols
2700 BC - Egypt, precision surveying
2400 BC - Egypt, precise Astronomical Calendar, used even in the Middle Ages for its mathematical regularity
1800 BC - Moscow Mathematical Papyrus, generalized formula for finding volume of frustums
1800 BC - Berlin Papyrus, shows that the ancient Egyptians knew how to solve 2nd order algebraic equations: .
1650 BC - Rhind Mathematical Papyrus, copy of a lost scroll from around 1850 BC, the scribe Ahmes presents first known approximate value of π at 3.16, the first attempt at squaring the circle, earliest known use of a sort of cotangent, and knowledge of solving first order linear equations.
But you can still continue to believe that Egypt only developed Mumies.
