All these things exhibit purposes in nature:
Consider the hands. They are skillfully useful for the intellect to work with.
Consider the legs and feet. They work in conjunction with your will to move, lift, stand, run, and work.
Consider the eyes. They allow us to see what we are doing. To identify objects and realities.
Consider the mind. It conceives from perception and constructs from reason and imagination. It forms memories for many reasons.
You are self aware.
Consider the ears that bring forth the sounds of actuality.
Consider language and the ability to vocalize.
Consider the fruits and vegetables that are vital to the nutrition of the human body.
Everything the body can do is organized for the convenience of being and actions. It enables us to act upon our motives.
Consider the heart. It is there for appreciations, joys, peaces, loves, enjoyments, fulfillment, relationships, conscience, wonder, awe, pleasures, character of being, neutralities, ambivalences, and identity of individuality.
Consider the nose. It breathes and smells the nature we live in.
The ability to communicate. The ability to understand and comprehend. The ability to embody characteristics of virtuous character. The ability to make logical deductions about important realities. The ability to weigh options. The ability to make judgments. To consider causes and effects or lack thereof.
We can think from the heart or solely from the mind.
The Human Body: To put things in the right places for the right reasons. And still get some aesthetic beauty out of it. And to get a measure of powerful, purposeful action potential out of it. To get a measure of effective efficiency and convenience out of it.
To produce art, and creature conveniences and necessities for life.
DNA uses coded information to construct body and being.
Again human life is a long, line of just right scenarios to exist the way we do.
The mind is made to know and remember.
The mind is made to think and figure out things to do.
The mind works with ideas.
The body is built to use the environment.
The mind is made to interpret and understand things for now and future reference.
We build our future off of our past remembrances.
The mind is made to see patterns and relationships.
The mind is made to identify things.
The mind is made to recall pertinent information.
The mind is made to interact with the environment.
The mind is used passively and willfully.
The mind is an intelligent construction.
As if God were a reality hacker.
The mind is made to create and build things.
The mind is meant to explore.
The mind is meant to learn things.
The mind is meant to construct meanings.
Meaning is a necessary part of existence because mind does all these things.
The mind is built to find phenomena and make meaning of phenomena it finds.
Mind and body are tools to learn, to act, to survive, and to remember for usage.
It is senseless to think that somehow all this functionality is mindlessly made. That pure mindless incident arranged things this way. Instead everything the body and mind are is meant for to do something.
If not a God then something intentional planted us here by way of natural forces. Evolution simply ignores the appearance of mind constructing life. It doesn't address the problem so much as glaze over it.
Science can't address the intrinsic nature of these phenomena because it is restricted to extrinsic observance of how the physical world works. The best science can do with regards to only consciousness is to find the physical mechanisms that enable it to switch on or off. That won't be an explanation of all the purposes found in life.
As to the nature of how God exists that is an incomprehensible mystery. Because of its incomprehensible nature it is ruled out.
There's mystery enough to compel the idea of God. Nothing is ideal in nature but we have just enough to invoke the mystery.
I'm always amazed at the contrasting intuitions of atheists and theists. It's to the point that each seems totally alien to the other. And much is assumed about the reasons why people go to one side or the other.
