Egypt has a ridiculously large amount of various primary sources you can refer to.
**Archaelogical
pylons
pyramids
tombs
stelae
ostrica
pottery
jewellery
exotic goods - e.g. scenes in the tombs of thutmose III and hatshepsut depict "offerings" from nubia. what does this tell you? they had a sphere of influence (often described as annexed with nubia) by this point in time.
housing remains
Pretty much anything that physically remains from the past.
**Written - remember much of egyptian archaeological structures are also written sources.
- papyri - spells, instruction texts, hymns.
- inscriptions - legacy, spells, hymns.
- receipts - deir el medina they had 'receipts' (only refer to this if relevant, while it's a pretty amazing feat they kept such records remember deir el medina is an elite workers village it doesn't represent the wider peasant/working class community.)
I'm sure you've been given plenty of resources which refer to sources you just didn't grasp onto what the term 'source' can equate to.
And remember a SOURCE is different to EVIDENCE.
Source = Remains from the past.
Evidence = The conclusions drawn from these sources.
Hope that helps.
