Why was being a tomb builder considered a very important job in ancient egypt?

The tomb builder's position in Egypt was very important because tombs were built for the highest persons in the land, the pharaohs, both as a monument to their greatness and to aid them in the afterlife.

The pharaohs' tombs were enclosed in massive structures, the pyramids. The most prominent example is the Great Pyramid of Giza, built for Pharaoh Khufu (2609 BC - 2584 BC). It is the only one of the Seven Wonders of the ancient world that still stands today. It is 480 feet tall, and estimates suggest that about 20,000 workers over a period of about 20 years were needed to build the Great Pyramid. So any persons at the head of a tomb building project, for any of the pyramids, was in charge of a gigantic undertaking of engineering and coordination of efforts.

biological/genetic factors means they were born or predisposed to have something. nothing can really change it, and you can't really do much to "fix" it. it isn't something learned

these are the biological factors:

adrian is relatively tall and he is on the basketball team

(adrian can't ever stop being tall or force himself to be tall. likely one or both of his parents are tall as well and they passed on the tall gene. he probably does basketball because he is tall)

the rest are environmental/cultural factors. these are things that are taught to us. for example, cynthia wasn't born saving pocket money, her family most likely taught her this (environmental factor)

hope this !
