when we're gone we're gone I reckon
Then what would be the point of life, if your thesis is true?
There doesn't have to be any point
You are a creature born of this earth but unfortunately your human trait tells you that you're important,and there must be a reason
you are not, and no there doesn't have to be!
why should you be any different from any other living organism on the planet?
humans are intelligent enough to be aware that one day they will die and so self preservation and selfishness kicks in and so you seek solace from somewhere, its human nature (another trait)
