Isn't it easier to prove God's non-existence than His existence?

I do agree that proving the existence of God is comparatively difficult than proving non existence.To prove that God exists,you have to study all religions and know the concept of God in the religions.The religions thus helps to know the existence of God.If we take a look at Holy Quran, we find it is the book sent by Allah to his messenger for guidance of humanity.The Holy Quran says,O MANKIND! WORSHIP YOUR LORD,WHO CREATED YOU AND THOSE WHO WERE BEFORE YOU.This the a part of the verse no.21,2nd chapter.If any body denies the existence of God then i ask how were you created?And if somebody believes that Quran is not a book from God,the holy Quran challenges the person in verse no.23,chapter 2 AND IF YOU ARE IN DOUBT CONCERNING THAT WHICH WE HAVE SENT DOWN (QURAN) TO OUR SLAVE (HOLY PROPHET) THEN PRODUCE A CHAPTER OF THE LIKE THEREOF AND CALL YOUR WITNESSES BESIDES ALLAH,IF YOU ARE TRUTHFULL.Till now no one has succeded this challenge.Thus it is a clear indication that there is somebody who controls the universe.You do need to go in details to find out your God,without which it is almost impossible.You must not judge a religion by its followers,but it should be on the basis of what the religion commands.Thanks.
