A "meta-argument" against all future arguments for God's existence ?

[Ferrocyanide]

Obviously, the intelligent design of nature is a delusion

An atheist shouldn't really talk much about delusions, you know.

Tell me, @Fake Messiah, absent a god, how do you trust your naturally evolved brain to be a reliable tool to investigate reality, and not a delusion? 

I disagree.
Also, you don’t know whether this god-alien’s universe has existed forever.
Right now, you have a story written by primitive men from thousands of years ago.

Tell me, @Fake Messiah, absent a god, how do you trust your naturally evolved brain to be a reliable tool to investigate reality, and not a delusion?

I ask the same question to theists:
With the presents of god, how do you trust your naturally evolved brain to be a reliable tool to investigate reality, and not a delusion?

Also, I will answer your question.
All animal brains are tuned up by nature to operate a certain way. Most animals have the following data processing abilities:
-graphics
-audio
-touch (pressure)
-pain (pressure)
-temperature
-taste (chemical)
-smell (chemical)

All animal brains seem to have the ability to collect data and they store. For example, they are able to memorize their environment, their colleagues.

So, in order to survive, you need a properly functioning brain.
The ability to do mathematics (linear algebra, calculus, compose music, painting, writing movie script, setting up experiments, producing new chemicals) is a side product of those abilities. It looks like humans are the only ones who have past the basics of nature and it looks like some chimpanzees as well.
For example, there is the case where a human though a chimpanzee american sign language and that chimp though another chimp.

Yes. And when they do mention God, they freak out, they blasphemed the Darwinian Religion:

Yes, when it comes to lifeforms, the theists are trying to insert their gods into it. Not surprising since theist regard themselves as the ultimate product made by their god.
Serious scientists don’t resort to aliens to explain reality.

None of this explains away a designer, you're just describing a mechanism.
Understanding the mechanisms of a watch doesn't explain away the watchmaker.

Everything is a mechanism based on what we have observed so far.
At the foundation, the mechanism are based on the properties of a few fundamental particles.
It is also easy to explain why nature is not capable of making watches and it has nothing to do with complexity.

Yes, I see people on TV getting raped and killed round the clock. and... so do you?

It sounds like you didn’t understand the question or you choose to pretend not to understand it.
If this god is omnibenevolent, why does he just sit around and watch? He doesn’t have any feelings? Is he comfortable sitting on his throne?

God already expressed his omnibenevolence when he created you and endowed you with life, health, income, shelter, and so on, and so on, and so on.. But, being the ungrateful moron that you are, you turn your back on him and complain about why people are getting raped. An eternal afterlife is enough (duh) to redress the dramatic injustice in this life, imagine a rapist getting 30 years of inhuman torture for his crime, I bet you will start to pity him despite his wrongdoing (after he got 30 years of relentless suffering) and think this is justice enough.. now imagine him getting 300 years like that, or 3000, ... Seriously, eternity is enough. And anyone arguing otherwise doesn't really understand what eternity means.

That’s not omnibenevolence.
When a father and mother have a child and take care of the child for years, they are being kind to the child.
The jewish god is the type of god who doesn’t get involved.

Health comes from genetics, the environments. There is no evidence of any jewish god doing anything.

Income and shelter is something that depends on the culture, the country. Some are less advanced. Some have hostile neighbors and are in prolonged wars.

But, being the ungrateful moron that you are, you turn your back on him and complain about why people are getting raped.

Control your emotions.
Try to act like a gentlemen.

Rape, torture, crimes aren’t things that I could ignore. I understand that you are comfortable with such things like your jewish god. I am not.

I disagree. Allowing injustice means that the jewish god doesn’t care about morals.
A rapist getting 30 y of torture doesn’t undo the rape event. It doesn’t solve the problem of allowing rape to occur.
I am not interested in torturing rapists.
I would leave that job in your hands. In fact, I would throw you in jail for torturing people.

I have noticed that for theists, justice often means to torture the criminal. Why do you want to do that? Does it bring your satisfaction?

And anyone arguing otherwise doesn't really understand what eternity means.

I don’t think you understand what eternity means.
