"In other words, I am proposing that the question I ask in the Original Post might very well be necessary for our continued evolution."
I tend to believe that for us humans it is sort of a curse--although I don't believe in curses, demons, etc. Perhaps a better description is it's a
condition of humanity and the power our brains have to apply reasoning and logic to questions that have no answers. Here's how it all makes
sense to me.
Why are new islands formed? It's not the product of conscious thought; it is a confluence of several geologic conditions. It is a process that
simply *is*. Or not.
Meaning has nothing to do with the process.
A squirrel does not awaken from sleep and think, "welp--time to go eat and then ensure continuation of our species." It's not the product of
conscious thought, although animals do feel hunger, etc., and are driven by it. But it doesn't occur to squirrels to wonder why they do it. They
simply *do*. Or they don't. The meaning of life is not a concept in a squirrel's reality.
Plants are the same way. They are a function of their component parts, and they simply function with no need for meaning, because meaning is
irrelevant to the process.
We humans, however, have the often troublesome tendency to seek an explanation for something we don't understand. Most of what we do (save for
autonomic lower-brain functions such as breathing, etc.) is done via a conscious thought process.
As we work through these processes, we are faced with many decision points that can take us in an unlimited number of possible directions. Making
these choices is often simplified by the introduction of things like past experience, cultural/religious/social mores, memetics, rules, and personal
expectations.
Because we're not 'programmed' to operate the same way that plants and animals do, our logic and reasoning force us to question our own motives; we
have to make choices. And there are a LOT of bad choices. Oh, I've made some of my own in the past, and I will make more before I croak, I
guarantee.
This extra brain power we humans have makes life really hard sometimes. Life is painful. Yeah, I know there are many animals besides humans with the
ability for higher thinking, but I'm fairly certain humans are the only animals that actively worship gods--and that fills a lot of the 'causality'
blank spaces for a whole lot of people.
Making life as good as possible for myself, my family and friends is important to me. I'd rather be exhausted from doing meaningful things, than be
well-rested from laying around doing nothing. That is what gives meaning to life on my little planet.
There's my version of 'because' to your question of "why." It works for me. I'll bet there are many different approaches that work great for other
people.
