Key teaching of PK movie

I watched the PK movie and liked it. The movie had an important teaching.
I discussed the movie with many of my friends. Unfortunately, even though they enjoyed the movie; almost everyone missed the key teaching of the movie.

In my opinion, the message of PK movie is that there are two Gods.

1. God has created us. We know nothing about this God. Anything said about this God cannot be proven.
2. Humans have created multiple Gods. These Gods typically punish us and demand sacrifices. These Gods are mostly cruel. These Gods exist solely for the interests of its mangers (so-called religious experts). The goal behind the creation of these Gods is domination of majority for the benefit of few.

The God that Hindus worship is wrong number. The Allah that Muslims bow before is wrong number. The God that demands confession for sins in Christianity is wrong number. The book worshipped by Sikhs is wrong number. Here, people worship out of fear of cruel God. The managers of these religions solely benefit from this fear.
