Good afternoon stella1231-ga and thank you for the question.
It?s near impossible to give the years in which fermentation and soap
were ?discovered? but if I had to go off of what I found on the
internet, I would say that fermentation was most likely ?discovered?
first given the following diagram.
2000 BC - - 1000 BC - - 500 BC - - CHRIST - - 500 AD - - 1000 AD - - 2000 AD

FERMENTATION: Beer recovered from the pyramids of the ancient
Egyptians reveal that the Egyptians were able to produce the fermented
brew using almost pure cultures of yeasts.
"...Before 2000 B.C. the Egyptians apparently knew that crushed fruits
stored in a warm place would produce a substance with a pleasant
intoxicating power. By 1500 B.C. the production of beer from
germinating cereals (malt) and the preparation of wines from crushed
grapes were established arts in most of the Middle East..."
"...There is strong evidence that people were fermenting beverages in
Babylon circa 5000 BC, ancient Egypt circa 3000 BC, pre-Hispanic
Mexico circa 2000 BC, and Sudan circa 1500 BC. There is also evidence
of leavened bread in ancient Egypt circa 1500 BC and of milk
fermentation in Babylon circa 3000 BC..."

SOAP: The historic record is clouded by the difficulty of
differentiating between any particular "cleansing" material and soap
in particular.
"The earliest known evidence of soap use are Babylonian clay cylinders
dating from 2800 BC containing a soap-like substance.
?A formula for soap consisting of water, alkali and cassia oil was
written on a Babylonian clay tablet around 2200 BC.?
?The Ebers papyrus (Egypt, 1550 BC) indicates that ancient Egyptians
bathed regularly and combined animal and vegetable oils with alkaline
salts to create a soap-like substance.?
?A soap factory with bars of scented soap was found in the ruins of
Pompeii (79 AD).?

?The first known WRITTEN MENTION of soap was on sumerian clay tablets
dating about 2500 BC. They were found in the area of the Tigris and
Euphrates river. The tablets spoke of the use of soap in the washing
of wool. Another Sumerian tablet, dating 2200 BC, describes a `soap'
[this author's `..'] formulation of water, alkali and cassia oil. The
Ebers Papyrus, a medical document from about 1500 BC, shows evidence
that Egyptians bathed regularly and that they combined animal and
vegetable oils with alkaline salts to create a soap-like (sic)
substance for washing."
