It really does not matter whether you believe in GOD or not. If you believe in GOD, what is the 'idea of GOD' which you want to believe? If you don't believe in GOD, what is the 'idea of GOD' which you don't want to believe? As such there are many 'ideas of GOD', whom people worship and pray. Some even worship a tree or a stone as GOD out of faith. There may be many other faiths also. My personal idea of GOD is 'omnipotent, omnipresent and omniscient'. I think 'GOD' is only a name given to some entity out of faith and devotion. What is that entity, which you want to name as GOD. I think the 'idea of GOD' was envisioned at a time when much of science was not known. Now, as science has developed to a great strength, can we review the 'idea of GOD' in terms of science, so that faith(the 'idea of GOD') can meet science.
