I don't think anyone can actually answer this question, especially me, but I guess I'll try because they always tell middle school students to try, and I'm in 7th grade.
I think the meaning of life is all about living creatures and nature, with the survival lesson of life using resources and whatnot. Humanity needs all kinds of varieties of resources to survive like food, as do animals. The meaning of life expresses the need of life in areas, and represents harmony and organization of the glories of life.
I hope you like this answer, and have a good night! :D
