To a certain extent, humans are creatures of childhood education. Childhood education and experience are a determinant on how a person is developed. From this perspective, to allow secular education serving as the sole agent to affect a person's development is never a good thing.
In a nutshell, humans buy into the concept that secular education is 'neutral' for the development of independent thinking. But in contrary, that independence is, perhaps without humans' own awareness, deeply rooted on the asumption that no God exists. So if this assumption is wrong, the impact to humans is disastrous. The much more intelligent angelic beings, if exist, will definitely exploit the 'weakness' of this human system, to make the situation far more disastrous.
That said. I did find that the angelic beings exploited this humans system, such that humans who go through this system all developed a fallacious concept that "you, a scientific person, should only believe something which can be evidenced", which is one of the biggest lies and deceptions I've ever seen.
Now how disastrous the situation is?
Just as prophesied, all humans who went through such a system are with a mark on their forehead (mind) and right hand (behavior) to fight God. That's how disastrous it is. Are they with independent thinking? I'a afraid not. Instead, they are all plagued with the fallacious thinking that "one should only believe something which can be evidenced" (the hidden message behind is one shouldn't believe God).
More likely, our education system is more or less like the Tree of Knowledge which Satan led Eve and Adam to eat from it. That's why the same day you choose to eat from it, the same day you shall surely die. Please notice that the Bible never said that the Tree itself is bad! The consequential situation however is disastrous.
