Outside human awareness, there can be no perceived purpose or meaning in material elements. They just exist as a consequence of unintended physical reactions. Human perception is essential to recognise intended purpose and meaning in an otherwise purposeless, meaningless, unintended universe.
The fact that we can recognise and conceive of information and its purpose is evidence that we comprise more than an unintended blip on the long journey to total entropy in a material universe.
...he asserted, without the first hint of evidence, reasoning, or logic.
In actual fact, the existence of purpose is explained by evolution. If you ask a "why" question, then it can mean two things: how come? or what for? The first is asking for a process narrative - something like "why are planets spherical?", the second is asking for a purpose - something like "why are ball-bearings spherical?".
When you ask something like "why does this organism have this trait?" - both come together - the "how come?" is also a "what for?". The how come is because the trait was a survival advantage and was therefore selected for, so it also has a purpose; it is useful for some purpose connected with surviving in the environment.
Hence, through natural selection, purpose enters the world - things are actually
for something.
The trait of being able to perceive and understand purpose in the human mind, also has a purpose that is explained by evolution.
