Have you ever thought about who you are? Where have you come from? Where will you go? What is your purpose on earth? What is this earth? Who is God? Where is God? What is God? What is death? What happens after death? Is there rebirth? Does the law of karma work? Is there a soul? What happens to the soul? What is the body made of? Have you ever stopped to think about yourself? Who are you and where will you finally go? Have you ever stopped to think about what you are doing and if you keep doing what you are doing, will you get to where you want to go?
The biggest problem is that people don’t know the answers to these questions and the bigger problem is that they don’t even seek to find the answers. We are so busy in our world that we don’t have time to ask questions. Therefore, the most important thing in our life is to ask questions about ourselves, about life, about God, to introspect, to go deep within, to find answers about God, about life and everything that relates to us. This will give us direction, this will create purpose, and this will lead us to understanding and achieving the true goal of life.
While there may be many questions that are listed above, we don’t need to narrow all the questions that I listed because the answers will lead to one concentrated point. All answers to these questions will converge to show us one true reality.
The answers to many of the questions you listed above can be found within God’s inspired word, the Judeo-Christian Bible. So your statement, to quote you: “people don’t know the answers to these questions,” is not accurate.
Mind you, the majority of people do not know the answers to most of your above questions. However, true Christians who have accurate understanding of scripture can answer most, if not all, of the questions in your OP–myself included.
My own personal philosophy with regard to all this at this moment in time : there is no meaning to life as such. One however can give meaning to ones own
life. There is no evidence for God. And so it is more probable he does not exist. There is no evidence for the afterlife. And so it is more probable that does
not exist either. And that on point of death you will be in an eternal state of pain free non consciousness. Although to be strictly accurate the physical you
shall have disintegrated long before. So only philosophically speaking
