Thanks Dr. J. I find this topic of early civilization fascinating. I’m now getting a clear picture of when civilizations arose in the time-line.
According to this, agriculture in Egypt started about 8000BC and the primary crop was wheat which today we know to be toxic. It seems odd that people say Egypt started about 3000BC, I doubt it would take five millenia to start a civilization.
I have heard that the Hebrew text which says Adam and Eve lived around 6000BC is why people say that Egypt starts at 3000BC. So I’m a little sceptical of the dates given.
Anyway, thanks again for the responses.
