Are there any special purpose in our life other than eating, drinking, sleeping, making merry, quarrelling, amassing wealth, criticising others and such other silly things?
The physical things, eating, drinking, sleeping, are not purposes but biological necessities that are common to us all.
Being loved and loving others is purpose enough for me. All others things, creativity, job satisfaction, etc. are to attain this purpose.
I think you may have slightly overcomplicated things...
I'd basically boil it down to just, "Eat, Shit, and Fuck."
The eating & shitting are obviously related: the soil from which the food grows is more or less composed (or composted! Ha!) of decaying plant matter. The most efficient way of synthesising this plant matter into a usable form for supporting a new generation of plant life is for something to eat it... then shit it out. Said plant life has produced both the oxygen and food sources integral to our evolution- the current product of this evolution being a creature so unclear about it's place in the world that it feels compelled to ask questions such as this...
I would assume the Fucking bit is pretty much self-explanatory: it's fun.
Yes there is.Literature science, love of outdoors.In essence a love of life which is a matter of luck as who is born and where they come into this world.To live well one needs food, shelter, sanitation and some disposable income to provide choice.If one lacks any of these items then existence rather than life is the outcome, a situation endured by millions around the world with little or no hope of escape.Hence if good fortunate smiles on us we should not complain about our lot but find our own meaning through our own actions.
There is only one intrinsic purpose to life, and that is to perpetuate itself. In order to do that, living things engage in eating, drinking, and eliminating waste to preserve themselves until such time as they propagate more of their kind. Humans and some of the animals we share the planet with create any of the purposes beyond the rudimentary. Humans have honed this purpose seeking to a fine edge and have thus convinced themselves that they are somehow special in the overall scheme of things.
