What are the conceptions of life after death in different cultures, and how do they influence their rituals and values?

I need to write an Essay on the topic described in the title. The Essay is called “in-depth work” atmy school. I have written an introduction that I find useful and would like to be in the essay:

I chose to delve into this topic because I find it extremely interesting how death and the values associated with it vary from culture to culture. Death and what happens afterward represent a mystery for which there is no univocal answer, and it is fascinating to observe how the beliefs related to this phenomenon, which unites all living beings, differ depending on cultural tradition.
It did not take long for me to realize that writing and researching would not be easy, given the complexity and breadth of the chosen topic. For this reason, I decided to group some cultures based on their geographical location and to explore the rituals and cultural values of each group in depth.
I structured my work by setting weekly goals, allowing me to gradually focus on each chapter and manage the research effectively.
