This is very intersting...complicated and shows the variables in life. Oh yes this is about the questioning of all things in life, about life, why life, and how is it life. "Exsistientialist dread" is the name of this thought process. But, don't be discouraged by thoughts like this. It is an elevated form of thinking. It does indeed make us unique from other animals...including our own kind...lol I too wrote something of a similar frame it is called "Forever Silent" it may be posted here...let me go look. OK, It was not there but is posted now. I do hope to see more of your work. Please do not feel as though you are insignificant. You are not. You ARE!!!
