The whole point of FTA (not FTT) is that "someone" tuned every constants so as it this universe is viable for the existence of life.
Let me quote some things:
"Implicit in the theistic argument for fine-tuning is the belief that the universe was created with humanity in mind as its ultimate end product. Therefore, those advocating this view must not only make the case for a universe fine-tuned to allow for the existence of atoms, molecules, stars, and life; they must argue that the universe was tailored specifically for humans. Hence, the fine-tuning argument cannot be successfully made without simultaneously making a cosmological case for human exceptionalism."
"In termsof both space and time, the vast majority of the cosmos is not merely inhospitable, it is outright hostile to human life. The observable universe, which comprises all the matter and energy that can be seen from our planet, is around 1070 cubic miles in volume. Generously estimating the habitable volume of the Earth to be 109 cubic miles,5 this means that only one part in 1061 of the universe is known to be amenable to life (that’s a 1 followed by 61 zeros!). By way of comparison, this is less than the ratio between the volume of a proton and that of our entire solar system.
As well, humans account for merely one part in ~1041 of the matter in the universe by mass, but even matter itself is far from being the dominant constituent of the cosmos. The universe is overwhelmingly made up of dark energy (~70%) and dark matter (~25%). Ordinary matter makes up a paltry 4–5% of the cosmos, and we, a less-than infinitesimal sliver even of that. The vast disparity between the human and cosmic scales hardly substantiates the notion of human exceptionalism that is endorsed by theists in the context of fine-tuning. It rather suggests that humanity is, at best, little more than a cosmic speck."
Lemme state the Second Law of Thermodynamics. In essence, the Second Law predicts that the universe of tomorrow will be less orderly—and therefore more entropic—than the universe of today.
More quotes:
"What would the universe look like if it had been created and fine-tuned from the start with humanity in mind? Certainly, one would expect that the vast swaths of the cosmos that are unnecessary for our existence would be absent. It could be argued that the existence of solar systems other than our own might serve to test believers’ faith to some extent, but the presence of hundreds of billions of completely separate galaxies beyond the Milky Way appears superfluous. The history of the universe up to humanity’s appearance on the scene should also be much more brief—after all, an omnipotent deity could surely conjure a species into existence instantaneously, without consuming the eons of evolutionary time apparently required under the current plan.
If the universe had been fine-tuned for humanity, one might also expect the study of nature to cause scientists to incline more toward faith, not less. This point in particular is one of the more remarkable failures of the theistic argument: as science reveals to us more and more about the world, theistic models of reality increasingly appear so implausible that they must be amended to conform to new discoveries. Too often we forget that the Judeo-Christian position, which was once generally accepted, placed the Earth at the center of the universe, with Heaven and Hell beyond a sphere of fixed stars. Until Charles Darwin’s time, theists held that the origin and diversity of life were best explained by the account of Creation rendered in Genesis. For this reason, from the theistic standpoint it is all the more deplorable that scientists are disproportionately and increasingly irreligious."
"If the universe was fine-tuned for human life by a thoughtful designer, one must acknowledge the appalling inefficiency of the creation process. For one thing, it has been estimated that about 99.9% of all species have gone extinct.8 God must therefore be credited with an act of destruction that is as monumental as his mass extinction caused by the global flood. One might be led to wonder why a benevolent and omnipotent deity should be unwilling or unable to fashion a species in his own image, without first preparing the way by eradicating countless lesser ones. God must, then, have created the vast majority of species with the intention of wiping them out well before any biblically relevant timeframe. The pain and suffering experienced by the last dinosaurs as they died from a mixed agony of starvation and thirst 65 million years ago is merely one such example among millions."
And:
GM Jackson: "According to the anthropic principle proponents, if the universal constants (e.g. gravitation, the strong force, etc.) were just a nose-hair off, the universe as we know it would not exist; stars wouldn't form and there would be no life and no us. That supposedly makes our universe truly special. To demonstrate just how ridiculous this fine-tuning argument is, consider the fact that no measurement in physics is perfect. All of them are approximations and have margins of error. That means the universal constants, that make our universe what it is, have some wiggle room. Within that wiggle room are an infinite quantity of real numbers. Each of those real numbers could represent constants that could make a universe like ours. Since there are an infinite number of potential constants within that wiggle room, there are an infinite number of potential universes, like ours, that could have existed in lieu of ours. Thus, there is really nothing special about our universe."
AC Grayling: " The fact that a human nose (use the letter X to symbolise the nose) is a necessary condition for spectacles to be perched in front of the eyes (use the letter Y to symbolise ‘spectacles being perched in front of the eyes’) does not entail that, because Y is the case, X is in itself necessary. ‘Necessity’ in the logical sense of ‘having to be so’ is not the same thing as the necessity involved in a ‘necessary condition’ – here things have to be so only relative to something else’s being the way it is. In the case of X’s being a necessary condition relative to Y, but not in itself necessary, X could have been different, and if it were so, there would, or at least might, be no Y. For example: if humans did not have noses, spectacles might be worn as goggles are, held before the eyes by an elastic strap.
This is just how it is with the universe. We humans are the Y of which nature’s parameters are the X. We exist because the parameters are as they are; had they been different, we would not be here to know it. The fact that we exist because of how things happen to be with the universe’s structure and properties entails nothing about design or purpose. Depending on your point of view, it is just a lucky or unlucky result of how things happen to be. The universe’s parameters are not tuned on purpose for us to exist. It is the other way round: we exist because the laws happen to be as they are."
Again, GM Jackson: "The claimof fine tuning is subjective. As I stated before, no measurement in physics is perfect. The amount of precision we demand can be increased or decreased at our whim. We could have an approximate measurement that has a huge margin of error and call it finely-tuned if we so desire. Theists, in particular, have a lot of such desire. They so badly want God to be an indispensable part of our universe's creation, so they see finely-tuned constants.
They also tend to sweep under the rug the following fact: the vast majority of our universe is hostile to life, and they fail to consider that another hand in the proverbial deck might yield a better universe than ours, one teaming with life on every planet throughout the cosmos."

And be as it may, socio-economic problems are part of our society..of our nature.. a powerful and all knowing creator/tuner would have realized that, yet he was not able to address that. And its not human stupidity, thought to some people that's the case, but our selfish nature that makes living here on earth sometimes so complicated. (Im injecting the selfish/selfless gene argument here, just to be clear.
)
FTA tends to make you believe that our universe was created with humanity as its main purpose, no..we exist because the conditons of our universe, this universe allowed us to exist.
The topic here is why some scientist believe in god and reiterating the FTA as its basis. Majority of scientific findings do not tend to lean on faith, but the opposite. So the argument being pointed here is not accurate.
