Every since we're born your main goal is to survive and Populate it's set and stone but when you grow you experience feeling you can't explain although scientists think over time they've have but you can't explain something you haven't felt yourself it's near impossible to live vicariously through someone that died over a thousand years ago. Nothing stays the same not even us we're changing everyday, every hour, every minute, second, even down to a nanosecond, even cordon copies aren't the same, they live different life's, there's a saying I have it's between life and death. "Life asked death, Death, why do people love me, but hate you? Death responded Because you are a beautiful lie and I am a painful truth." It's the truth you don't live forever not even God did, it's almost as if our life purpose is to just distracted ourselves from the painful truth of death, I guess what I'm trying to say is we don't live forever and I know that but it's a painful truth.
