Was Ancient Greece in Ancient Egypt?

No. The two terms refer to almost completely different regions and times, though the influence of what we call "Ancient Greece" certainly extended to portions of what had, at one time, been "Ancient Egypt."

Greece was not located in ancient Egypt. It is in southwestern Europe, across the Mediterranean Sea from Egypt in northern Africa. The ancient Greeks were among the first modern societies to study the ancient history of Egypt. Many of the translations of hieroglyphics are based on the Rosetta Stone, which had text written in both hieroglyphic form and in Ancient Greek.
