Ok. First of all I am an atheist, so from my viewpoint, there is no afterlife, saviour, heaven etc etc.
Now given that, and maybe I should address this purely to atheists, but for now, maybe not, lets's give it a try on an open forum... Although I really don't want any bible/koran quotes/arguments please?
Anyway back to the point...
Does ANYTHING matter?
We spend our lives worrrying about possesions... Money...Cars, bikes, clothes, computers, mobile phones, hairstyles etc.
People... Friends and family, our neighbours, the locallity, the country, the world, poverty.
The planet... Polution, population, resources, greenhouse gases, global warming etc.
We elect governments, or live under dictatorship.
We believe in deities and worship them, or not.
We are born, and we die
The planet has been around for maybe 4 or 5 billion years, and will be around for a while yet.
But when it dies, then the galaxy will be 99.9999999999etc % unchanged.
We are irrelevant. People are irrelevant. Animals, plants, the days and nights...are of (almost) zero relevance when it comes to the galaxy, never mind the universe.
Or what?
