I agree with what you state. Egypt was a African civlization with a African based culture. Most people in the academic world have embraced this.
During the pre-dyanstic there was a population of the Nile Valley within both the Nile Valley itself,Horn of Africa,and the then fertile Sahara. The Delta and Lower Egypt I am not so sure about. Very few studies have been on this area because its below sea level and material decomposes very easily.
Anyway, here is pretty much what modern Egyptologist say about the ancient Egyptians:

Subject: Re: Egyptian Ethnicity [long]
There is no doubt that the subject of the ethnicity of the ancient
Egyptians=
=20
is one
that is highly charged. Emotions tend to run high regarding this
topic. A=
=20
significant
exception are those purely scientific studies written by human
biologists=
and
anthropologists studying the human remains from Egypt and Nubia. =20
Thankfully, the
cool light of reason still prevails in that area of endeavor, and it
is=20
there that the
debate on Egyptian ethnicities should be carried out. Actually, there
isn't=
=20
much of a
debate in those circles. It's very clear that, in general, the
Egyptians=20
and Nubians
were fairly heterogenous folk physically related to each other early
in=20
their history.
Because such studies on the physical ethnology of the Egyptians and
Nubians=
=20
often
pertain to paleobiology and paleopathology, I have been including
these in=
my
BIBLIOGRAPHICAL DATABASE OF ANCIENT EGYPTIAN MEDICINE AND
MEDICAL PRACTICE. Currrently, I have 153 ethnological/biological
studies
catalogued, of which 51 are from 1945 and later. I use 1945 as a=20
watershed-date in
this topic, since it marks the date of el-Batrawi's first of two
landmark=20
studies of
Egyptian and Nubian crania, which (as I interpret it) marks the
beginning of=
=20
the end
of the dynastic race theory (despite holdouts such as Derry and
Emory). In=
=20
addition,
the work of the two Berry's and Evgen Strouhal cannot be overestimated
for
understanding this subject.
With these thoughts in mind, I have prepared and included here a
printout of=
=20
these
studies. Most of these should be used as a basis for understanding
Egyptian=
and
Nubian ethnology and racial affinities. Many of these are primary
research=
=20
studies;
others are anthropological syntheses. Admittedly, a few deal more
with=
cultural
issues rather than physical evidence. I _especially_ recommend the
works of=
=20
Brace
et al. 1993 and Ortiz de Montellano 1993 as good examples of
confronting=
faulty
methodologies for ascertaining Egyptian ethnicity.
Please keep in mind that this bibliography is nowhere near complete,
nor do=
=20
I claim
any measure of completeness for it. If anyone wants to receive the
listing=
=20
of the 102
pre-1945 studies, I will gladly transmit this off-list. Those works
pertain=
=20
mostly to
notions of dynastic race, "pure race"-theory, and racial diffusion (a
la G.=
=20
Elliot Smith
et al.).
Finally, let it be said that the ancient Egyptians were not white=20
Caucasians, nor were
they Indo-Aryans. They were African, primarily a brown race, although
fair=
=20
skinned
and leptorhine in the north, black skinned and platyrhine in the
south, and=
=20
various
shades in the middle. They manifested all the physical differences
you=20
would expect
in so large a continent as Africa. Trigger (see below) uses the
term=20
"Nilotic" to
refer to their heterogenous character. When all is said and done,
though,=
=20
this whole
question of Egyptian racial identity says more about us today than it
does=
=20
about the
ancient Egyptians.
