How will you explain to your children...

[Walking Void]

Maybe You should tell them that "purpose" or "intention" is not part of the way ANYTHING works. Purpose and intention are human inventions used only in planning. Eg: "Hey dad, why do I have to eat?" - "You have to eat if you are to continue living. If you stop eating you will starve." - "What is starving, and why do we starve?" - "Starvation is a state of human health. It occurs from a lack of nutrient energy, which is what you get from not eating. If you stopped eating, your body would slowly consume itself. It would start by consuming your fat, which is stored energy in the body. After your fat mass reaches a certain point, your body would start to consume other body masses, like muscle or plasma. Eventually your organs will dwindle away and you will lack immunity and be hypersensitive to any type of illness or disease... whether it be cholera or total organ failure."

And so on. Use the internet. Information is at your fingertips, You can almost feel it.
