I can choose my clothes but I can't choose my beliefs
You couldn't be a scientist then, for example. You wouldn't be able to change your beliefs when faced with new evidence. The ability to choose what you believe is a perfectly ordinary requirement we place even on fairly average people.
On top of that, experimental results can only inform a subjective model for each individual. For example, children are informed about our solar system in a simple 2d plane, because that's useful enough. We can prove that the solar system has planetary deviation from the generally flat plane (up to 7 degrees) but that more advanced model is something that is generally learned later, out of pragmatism. You can spend a lifetime learning details and data, but you'll still die ignorant because gathering all of human knowledge is impractical at this point.
Therefore, relying on science alone, is not enough to inform your personal ideas about reality, even if you believe that it's the most reliable way to do so.
eg https://www.ncbi.nlm.nih.gov/pmc/articles/PMC300808/ <-- no double blind for parachutes, where's the evidence?
This is a common belief people hold to protect themselves from altering an existing worldview (or previous statements). I'm not sure how you construct a view that the belief in the scientific method and various derived conclusions (eg atheism or agnosticism) as the "correct" way to explain everything in reality, is not a defacto religion.
> For example, the scientists' religion don't really alter the research if they strictly follow the scientific method. In other words what they think won't alter the reality.
Reality is not altered by any religion. Not sure what this has to do with the belief in the scientific methodology.
I didn't say it's correct, I used the word 'approximation'. Because it's never about the result, it's about the process of 'proving' and 'provability'. And in this sense religion and scientific method/framework is orthogonal. Because it doesn't matter what the person's religion is, they carry out the same scientific process, and the answer to their religion/belief is always 'i don't know. not provable'
> Reality is not altered by any religion. Not sure what this has to do with the belief in the scientific methodology.
But that's the fundamental differences. How do you get to know the reality through religions? How do you decide which religion is the truth? If someone forms a religion by Harry Potter just like the Scientology, how do you pick and choose? Suppose religions is a big set, and new religions getting formed, how do you pick? But in the framework of science this kind of result doesn't matter. Because in the scientific methodology you go through the process, and that's the important part. You can choose to believe whatever religion shaped this reality you like and that doesn't affect the scientific method itself. Scientific method is a tool you can use, it doesn't give you answers to all questions(provable), and it doesn't need to.

I don't understand your definition of religion. As I understand it, religion is a set of beliefs that allow explains reality and allows you to reason about it. The idea that it inherently includes an omnipotent being is a particular definition that made it into some dictionaries and is now taken (ironically) as gospel. See the wikipedia entry for Religion (disambiguation). Religion is not solely about explaining the source of reality, but can be part of it.
He is learning about the world and for now I am manually putting my beliefs over him so that he can make some sense of the world.
I am going to be proud the day he manages to remove them and and put beliefs in his mind by himself.
In my opinion deconstructing the opinions you were given as a kid is part of the process of growing up. Thing is, it is an optional part and too many people grow up without going through that stage.
I hope your boy keeps giving you reasons to be proud of him, whatever kind of proverbial clothes he decides to end up in.
You can very clear choose any of both, but you have methodological and societal restrictions on both, on differing ways so you can't choose either one freely.
