Science suggests every part of the body has a purpose. Heart, lungs, bones, kidneys, liver.
A womb has a purpose. As do the genitals. Both genders have a purpose.
The hands. Look at them. The way it can twist on a wrist. It's for something. It has purpose.
DNA code is so complex, by description it would take 1 person 50 years to write. A, C, T, G,
The brain is a biological processing engine that's more efficient and flexible than any computer we've made. It controls all the organs automatically alongside other functions. This too has a purpose. I'd reckon part of its purpose is to also experience being human.
Everything in life is borrowed. Including what you think is you. While space and time are unified, you're just a spark in time as much as you're small to space while being a part of the universe. You are made of stardust, Science knows this.
Our purpose is to learn and experience. For some, the hard way. Science doesn't contest any of this.
Learn as much as you can, or not. We'll find not everything we know is important.
Yes many of you will die a jackass, but you would have still served a purpose and that is, being an example. Yes there have been many jackasses, but the nervous system filters out the consciousness to experiencing being what it is for every vessel, the illusion of duality, and in this point in time or new perspective, you're not surrounded by every vessel, so the jackass will be on display yet again. We do learn from others what works and what doesn't.
Sure we're not like the other animals. It isn't difficult to see unlike them we're held accountable for our actions on a deeper level. And I say on a deeper level cause even the animals must at times cast out their own.
And yet at the end of the day the brain is a sack of perishable fat. A dead person by definition cannot be a jackass. Eventually nothing will function further proving nothing ever did to begin with.
When the body ceases to function, it doesn't dismiss the fact it served a purpose.
A dead inventor leaves behind inventions.
