The fear of the God injected by the religion was the root cause of worship, superstitions, and dogmas.+

The Bible says: ~ God is a Spirit, and they that worship God must worship God in spirit and in truth. (John 4:24) 

The Spirit is the root element of the universe. The Spirit is present in the form of the Soul, the innermost Self. The Soul is present in the form of consciousness. From the Spirit, the universe comes into existence. In the Spirit, the universe resides. And into the Spirit, the universe is dissolved. The Spirit is the parent of all that is there is.

Yajurveda – chapter- 32:~ God Supreme or Supreme Spirit.

Vedas and Upanishad confirm that God is the Soul, the Self, is present in the form of the Spirit or consciousness.

If God is a formless Spirit, then how does man know God created the world? There is no proof. If man had seen God creating the world, he could admit it, but how could he have seen God before he came into existence? (i.e., were created).

The religion preaches that God is one and the ways to God are many. It simply tries to lead them to darkness with its dogma and idea of many Gods, which is apart from the Self.

People all over the world in the past and present have accepted the idea of the existence of God. 

The fear of the God injected by the religion was the root cause of worship, superstitions, and dogmas. The religious belief is passed on to the populace from one generation to the next generation

God in truth, we do not see is real. God in truth is hidden by the illusory world in which we exist because the world in which we exist is created out of God in truth. From the standpoint of God in truth, the world in which we exist is false.

In Atmic reality, the world in which we exist does not really exist, and what does not exist for us really exists.

By worshipping God in human form, repeating mantras is like watering a barren soil. The seeker of truth should not waste life in empty formalities. Without realizing the world in which he exists is an illusion it is impossible to acquire Self-knowledge or Brahma Gnana or Atma Gnana.

The mantra-yoga, consisting of repeating the name of God, or even the AUM, thousands of times yield nothing. It can appeal only to the ignorant, to those who cannot think deeper. It is a mere religious fable. The real exercise is to think of the meaning of the name or the AUM, and only then do you get something.

Mantras can do nothing. If they really have any power, why don't yogis use it to stop all the wars, terrorism, and epidemics? 

All the magical powers of mantras are a religious fable because religion is based on the false Self(waking or ego) and false experience(waking or the world). Visions and Samadhi are illusions from the standpoint of the Soul, the  Self.

That is why Sage Sankara: ~ VC- 63. Without causing the objective universe to vanish and without knowing the truth of the ‘Self’, how is one to achieve Liberation by the mere utterance of the word Brahman? — It would result merely in an effort of speech.

People of small intelligence follow religion and believe that the world was created by God. But how do they know that He did so? When a pot is created, one can see both the pot and its maker, but not in the case of the world.

By believing and worshiping what is not truth (God), one is in the prison of the dualistic illusion. Truth realization or Self-realization is God realization. Self-realization is real worship. : ~ Santthosh Kumaar
