Mainly, the ancient Egyptians communicated in writing and hieroglyphics heratic. Like most people could not learn both languages, after all, the hieroglyphs are more than 700 characters, to select the people called scribes, learned the language of ancient Egypt to write for other people. People write things like the harvest of the month, or what was done during the week. People also communicated through games and drama, to express their feelings and thoughts to viewers by acting on their thoughts.
In these games, only men were actors in the game, because women do not have many rights. People also naturally talk to each other to see the events of the day and what was happening. They also speak to communicate with their gods to pray and thank them and ask for help with problems in their daily lives. The ancient Egyptians would also communicate through drawings, photos, and snapshots of their lives, and the only thing important is happening. They also drew to express their prophecies and predictions for the end of the world.
Another way the Egyptians were able to communicate through their art. They show pictures of their ships on the gods and demigods (children of the gods) who do heroic acts to save the world. To communicate their rank, people wore clothes more expensive, and their houses were larger and fully furnished with richly carved furniture and impressive works of art. Women also wore gold and lapis lazuli jewelry. The Egyptians began to form a pictographic written language about 5000 years ago, where they continued in use for over 3500 years until about 400 AD.
Finally, the images they used to represent words came to represent sounds. These symbols, hieroglyphs, or "registration" sacred have been adapted for use in everyday life, in addition to their religious / mystical importance. Some hieroglyphs are very complicated and take some time to draw. The word comes from papyrus paper, a reed grown large by the river Nile. Egyptians used papyrus to make paper for written communication. The ancient Egyptians used symbols to say something so it would be easy to recognize immediately.
Some symbols were knot of Isis (fertility symbol), Ankh (symbol of life), crook and flail (symbol of authority), etc. Development of written communication in the form of ancient Egypt to become one of the greatest empires of his time. They invented writing, measurement, and calendar. It has affected their culture. Hieroglyphic writing was how ancient Egyptian writing photos like a duck, a 3-line which means a river, etc. With the knowledge they have they really improved their standard of living.
Hieroglyphs were used for most surviving forms of written communication in the ancient times and Middle Egyptian, at least for official documents, hieratic was already used for day-to-day administrative needs during the Old Kingdom. The religious texts in the demotic time were also generally written in hieroglyphs when they were placed on the temple walls and stelae, hieratic was used for religious documents on papyrus. (Works Administration were of course written in demotic.) The last datable hieroglyphic text was written in 394 AD.

While the shapes of the hieroglyphs are indeed taken real (or imaginary) objects, most of them are used for their phonetic value. Take, eg: the hieroglyph representing a house. It can be used to write the word (vowels unknown) pr which means "house". The ancient Egyptians used hieroglyphics for over 3500 years (until 400 AD). Then they used the Greek alphabet with some added extra letters to represent Egyptian sounds. This form of writing was called Coptic.
Coptic was eventually replaced by Arabic, spoken in Egypt today. The ancient Egyptian language has faded and was forgotten. The last hieroglyphic text was written 1600 years ago. Since then, we had no idea what the hieroglyphs represented, so they made their own translations. They decided they were magic spells and secret religious songs.
