But your version of keeping your feet on the ground entails the sacrifice of your ability of excercise free will.
Free will is that thing which you have signally failed to demonstrate that human beings possess and which recent developments in neuroscience suggests - I will stick my neck out and say
increasingly suggests - is an illusion.
You are just a blob of matter resulting from unguided forces of nature
We're all that - you, me, your children, the fly battering itself against my kitchen window yesterday until let out, the aphids that cover the lemon balm in my back garden. Why is that such a monumental problem for you, Alan? Are you so existentially insecure that your existence has no worth until and unless you think yourself the special creation of a personal, conscious agent? To me that seems to be the essence of religion. I find that extremely weird. Here I am, an existent in the world just like you are, what Sartre called
ętre-pour-soi and not
ętre-en-soi. Don't fret; this is only something that Sartre devotees really need bother themselves with, which amounts to Gary Cox - arguably the foremost Sartre expert in the Anglophone world today - and me and a few other people who don't get out much but read a lot. My world is not the world that you describe.
with no meaning or purpose.
You forget, or are unaware, of the difference between proximate and ultimate meaning/purpose. Personally I'm absolutely fine with proximate meaning and purpose. I see absolutely no reason to think that there is any such thing as ultimate meaning/purpose.
You are just a trivial accident in the dimensions of time and space.
'Trivial' is the problem here. That's the word/concept to which I take exception. Otherwise, yes, absolutely and entirely. Why is this a problem?
But I can assure you that you are much more than that.
No you can't. You could assure me with a rational argument based upon sound evidential principles and a case based upon an interconnected series of mutually reinforceable evidence-based statements.
You have been created
By my parents.
and you are loved.
By the nearest and dearest - family members; friends - who love me.
A statement of the bleeding obvious if ever there was one.
