Everyone born atheist untill society starts to brain wash you.
In every society, there are, and have been (and may continue to be), unbelievers who ‘suffer from' an experience that gives them faith. They hear a voice, receive a vision and experience something unique and life-altering. They become a prophet, and a religion is born. To this I can only offer the cold, hard, shatterproof logic of my avatar, who observed:
“It is a contradiction in terms and ideas, to call anything a revelation that comes to us at second-hand, either verbally or in writing. Revelation is necessarily limited to the first communication; after this, it is only an account of something which that person says was a revelation made to him; and though he may find himself obliged to believe it, it cannot be incumbent on me to believe it in the same manner; for it was not a revelation made to me, and I have only his word for it that it was made to him.”
Thomas Paine, The Age of Reason, 1794
Consider how different the world would be, particularly with regard to the existence of religion, if everyone discounted so-called revealed wisdom, whether in speech or text, and insisted only on first-person communication from a ‘supernatural’ entity. Absent our own burning bush, angel Gabriel or observed ascensions, we are obliged to disregard such fictions!
Everyone has the same tendencies to sloppy thinking, agency inference, confirmation bias, and difficulty handling self-awareness (fear of death). That doesn't make them theists, but it makes them super vulnerable to becoming theists, because theism promises answers / fixes to the dread of mortality and other unknowns and uses the limitations and flaws in human thought processes to gain purchase. So for a child not to succumb to magical thinking, it requires not only that they not be taught magical thinking (although that's certainly a start) -- but that they be steeped in its very opposite. If a child is not taught critical thinking it may actually seek out religion or other forms of woo.
