If we're talking about Sinuhe, that's on the wrong side of the Late Bronze Age systems collapse. Other than perhaps faint echos found in the Greek epics and the Hebrew scriptures, Mediterranean texts from the other side of the collapse were undeciphered until the 19th century. Ramesses II and Alexander are more than eight centuries apart, with Alexander being on our side of the collapse.

On the other hand, that Greco-Roman culture that was so influential is in no small part Egyptian. Alexandria was a major cultural center of the Greco-Roman world. Egypt was the first nation to convert to Christianity en masse and that influence on Christianity remains today.
