It means they are a thing, an entity to be experienced and described. Moreover, their cohesive sensory nature is what makes their existence all the more amazing because as you say they are the byproducts of electricity and tiny drops of chemically laden blood in the human or animal brain.
Wallahi, its actually amazing how someone walks out into nature everyday and is surrounded by an infinite number of perfectly functioning beings (animals plants air) that are essentially organic machines and still chooses this attitude.
No one denies that the systems in the universe are not amazing we simply deny that a magical super being created it and sent a book down to an Arabian Bedouin 1400 years ago. This is clearly a sad attempt at a straw men argument.
Furthermore , nature is not perfect. If it was perfect , whatever that metric implies, it wouldn't constantly evolve into new systems to compensate for its deficiencies.
Side note: Infact , the word "perfect" is arbitrary and is simply a maximum ideal humans use to reduce "thinking load".It is much easier to think black/white instead of a continuous spectrum of dimensionless ideas.
It shows that you and your elk are simply choosing to ignore the miraculous nature of everything around you. I mean if a drop of LSD can make you feel euphoric or trippy with that little brain of yours, what do you think a planet where the atmosphere is LSD is would do to a brain evolved to handle it? If you and this entire universe and this perfectly functioning planet are currently existing off of a statistical impossibility, why cant it reoccur? If science can go from discovering DNA in 1953 to gene editing in 2019, what makes you think that by 2500 we wont have discovered the essential compound to each being that would regenerate into that being given the right conditions in the same way that a torn meniscus regenerates itself?
My brain is , on average, equal to the size of most other brains. LSD and other chemicals simply expose the superfluous nature "feelings" are predicated on.It exposes that there is nothing miraculous about the way you feel and infact any interpretation other than "meh" espoused onto it is due to ignorant interpretation.
"Science" is a concept , it's scientists who discovered physical laws the universe is based on and allowed others to work around it. Moreover, all non-muslims simply deny the ludicrious concept of islam not the innate beauty (which is based off superflous feelings) of the world. I'm not sure of anything however I hedge my bets on religion being fake.
The reality is that you are
Ignoring the fact that your existence is a statistical impossibility
Presuming that it can never ever possibly occur again and that the "chance" that sprung your entire existence is the only unique miraculous universal event.
Making yourself blind to everything you come across everydsy. I mean you are talking to me right now though metal and invisible waves. And in an hour, you will eat the flesh of an organism that just do happens to sustain your life force.
Finally, you and every atheist and ex muslims are cowards. You have not been accepted like you thought you would and you do not have peace. As i talk to you about islam and Allah, two things i love, you re talking to me about islam and Allah, two things you believr are fabrications. A person who spends his time talking about things he believes to br fabrications is either deluded or is too cowardly to admit his true belief of those things.
I am not denying that my existence is a statistical impossibility nor affirming it. However if there is a statistical probability of me re-existing in an infinite cosmos, then it doesn't matter.An infinite amount of time allows rebirth and thus we exist after X billion years (a lot of time...) of waiting.
E.g , after 10 billion years I came to "life".
I am not a "Coward" and am not looking for acceptance from you. I spend my time exposing liars and sheep , it is a noble effort I spend a few hours on randomly.
To recap your argumenta skills are laughable, and since you believe in islam I assume your critical analysis is just as dismal.
I bid you good day and happy hunting.
