Driven by experiences with aging and death of related persons, I am very interested to hear what other people with scientific/philosophical background do think about this fundamental question. Certainly, religious answers are very interesting. However, these cannot be really proven. But this is a prerequisite of reliable research. Certainly, Monty Pythons cine film ``The meaning of life'' is big entertainment. However, it cannot supply us with actual answers. Therefore, let me here further ask you: Going beyond my first attempt to answer this question, which is compactly presented in doi:10.13140/RG.2.1.1226.4165 (part I) and doi:10.13140/RG.2.1.4601.5209 (part II), are there theoretical attempts pointing into similar directions?
