Salvation is not the same as enlightenment.

Even Buddah will be judged for his sins if he does not accept Jesus Christ.

The tree of knowledge, the fruit, was stolen. All those concepts are considered the forbidden knowledge and are alternative paths to enlightenment/communion with God, but those paths don't forgive the sin that keeps people out of heaven.

In most cases in fact, englightenment is more about accepting and coexisting with evil rather than trying to confront and destroy it. Being enlightened is like being lukewarm so to speak. It's a method of talking around good/evil being part of the same thing, symbolized with the checkered floor in Masonic temples.

Revelation 3:16

So because you are lukewarm, and neither hot nor cold, I will spit you out of My mouth.
