One plausible theory is that the knowledge is encrypted in our brains and it somehow is decoded

The OP doesn't understand the Mathematical meaning of encryption/decryption and doesn't understand how it's different to encoding/decoding.

Encoding is a reversible mathematical transformation:

encoding(X) = Y

decoding(Y) = X

Encryption is a reversible mathematical transformation where

given a secret key K:

encrypt(X,K) = Y

decrypt(Y,K) = X

If knowledge X was encrypted and stored in your brain as Y then you are still left with two questions:

1. Who has the decryption key K?

2. What is the decryption function?

I won't even bore you with the details of symmetric/asymmetric encryption.

Thank you for the correction. I think I should have used encoding instead of encrypting.

One plausible theory is that the knowledge is encrypted in our brains and it somehow is decoded as a result of mental activity becoming ready for experience. Where the knowledge comes from? Evolution, by chance. Basically those creatures who by chance have more knowledge could survive better. What do you think? Do we acquire knowledge through interacting with reality or we just got it by chance? In first case, how do we acquire knowledge?

Plato had a similar theory, so you are in good company. He thought that knowledge was recollection of knowledge gained in past lives. Now, I don't know how his chain of events began - i.e. how things were learned in the first life, but in later lives his theory resembles yours.
