The correct answer to this open question is the following.
A traditional Tomb, like those in graveyards in the United States, is a common one, used to bury dead people. Some times it can have an ornament or two, and the most luxurious ones can be in the form of a small chapel.
The tombs in the pyramids of Giza, Egypt are majestic because they were designed to bury emperors. The tradition in those years of ancient Egypt was that the Emperor -as a descendant of the gods- had to be buried with all their riches and necessary things for their trip to the underworlds. That is why, when archeologists discovered these tombs, they were magnificently prepared with oils, vessels, and ornaments.
