I was thinking about whether we had childrens and then left them in a place where they could learn everything except religion or faith
From what we know of anthropology, odds are that they would eventually develop animistic or paganist beliefs on their own. Full-blown theism (not necessarily monotheism) would probably come at some point.
No one will find faith in Jesus
They will not imagine that there is a god who came to earth to sacrifice himself
Some might. After all, the idea began somehow in this world, why would it not arise in this hypothetical world of yours?
Likewise, other religions such as Hinduism or some of the Buddhist sects that believe in the incarnation of Deity or even Baha'i
I am not sure that such Buddhist sects actually exist. None come to mind.
They will never believe in any deity on earth because they will think they are a human element but it is mathematically or educationally superior
Again, I doubt it. Theism occurs naturally. But it would not have to be quite as influential as it is here.
Also, and this is probably relevant, it is doubtful that spontaneous theism would include "creator of existence" as one of the roles of its gods.
Historically, Ibrahim's God is one of the very few that have such a role.
But they can easy think about that there is a great Creator outside the field in which they live
This is what I want to deliver
What if a world war occurred or we moved to live on another planet and lost all the information related to the scriptures
Then other creeds would develop on their own, as they always do.
All beliefs will disappear, and only faith in the existence of hi Creator, the Risen One, which is the ancient God that Jews and Muslims believe in, will remain.
Actually, I expect that one to become extinct. It is a particularly vulnerable belief, which is probably a main reason why it is so fond of proselitism.
Faith in Jesus or any faith in human existence on Earth will not survive
I am not sure of what you mean by faith in human existence on Earth. We know for a fact that humans exist on Earth, after all.
Only the belief in the existence of a great supreme creator over the heavens
Unless it fails to develop on its own, which is a very real possibility. Creator Gods are not very significant for religious practice, after all.
Children's who grow up without religions will have a questions of where they came from and will not be atheists
Quite the opposite really. Religions will develop on their own, I have no doubt. But they will generally be far less prone to theism, and particularly less prone to monotheism, most of all of the Creator God variety, than Christianity and Islaam have shown themselves to be.
Atheistic religion is all but unavoidable, and generally speaking a very good thing.
