Who created God ?

I am confused Series

 CREATOR

The Universe is not beginningless as said by Aristotle .

Cosmologists have proved its beginning.

The Universe had its beginning from the point of singularity.

Cosmologists have sufficient evidences to prove it.

When did the Universe come into existence ?

Scientists say nearly 1500 crore of years ago.

The earth was formed about 450 crore of years ago.

Human being evolved 2.5 million years ago.

Hawking and Penrose say , there was a ' point ' in the beginning.

This point is called '  Point of singularity ' which exploded with a Big bang . 

Someone should have triggered the explosion, Who ?

Many accept  that  that  first cause is GOD.

When Science was a baby,

Religions were parents and grand parents.

What the religions commanded were obeyed.

When science has grown, religious doctrines were questioned.

"  The earth is the centre and the sun and the planets orbit round it ".

Catholic religion believed this , accepted  and propagated it.

Copernicus ( 1473-1543 ) contradicted and said, 

' The Sun is the centre." ( heliocentric )

He was troubled by the religious heads, 

his book was not allowed to get published.

When Galileo endorsed the same, Church was annoyed,

He was kept in the house arrest till his death (1642 ).

Galileo suffered from total blindness  in his last days.

In 1992,  Pope Paul II offered official apology for the injustice done to him. 

Darwin's (1809 -1882)  findings shakened many of the  religious beliefs.

He was the man who changed man's thinking.

His theory of evolution was rejected by the Church.

After 126 years, Church of England apologized.

Science had proved beyond doubt that the Universe had a definite beginning.

Jainism even to-day says that  the universe had no beginning and  end .

Buddhism still  doubts the creation theory.

For Buddhists, the question on the origin of Universe is worthless.

Jainism says, ' no creator for the Universe' .

Buddhism says neither yes  nor no to the creator.

Christianity, Islam, Bahi Faith and Sikhism say ' yes ' to the creator. 

Hinduism teaches that Brahma is the creator of  the universe.

It is an easy logic that without a creator the universe would not have come into existence.

Why Jains and Buddhists are not accepting this logic ?

When I was explaining this logic to some of my students,

One has asked , " apply the same logic  and tell me sir, who created God ? " 

If the universe needs a cause, why not God need a cause, who created God?

Is there answer ? God is the uncaused Being that caused everything to come into existence. 

He needs no creator, He is the creatorless creation who created all  the creations.

God's existence cannot be proved by scientific methods or experimental tests. 

Belief in God is affirmed  only by  faith. 

Is there any  other convincing  answer ? 

I am confused.
