No one is lying about God, it is just that many are seeking and have not yet found.
A VERY large proportion of the earth's people believe in the same God, whether he is called Jehovah, Allah or just God.
Science is NOT antagonistic to the concept of God, in fact it compliments that belief very nicely. In science Occums Razor applies to virtually everything, the simpler the explanation, the more likely it is to be true. Yet, the more we discover about our universe, the more COMPLEX it becomes.
The Christian Bible, the Koran, the Jewish Old Testament, and a host of other "Holy Writings" are often mans attempt to explain the unexplainable. When it come to the Bible, it is amazing at just how accurate it's history is, towns are where the Bible says that they should be, towns were destroyed catastrophically as the Bible says that they were, etc., etc.
At one time, most of the Near East and Europe believed that each and every word of the Bible was inherently accurate. As time has gone on, and as we have discovered more and more about how things work, we discovered that much of it is essentially a parable. That does NOT however mean that it is all bull manure.
You are free to reject belief. I am free to believe. We were given "free will" to accept or reject. I choose to believe that there is an all powerful deity responsible for this universe, and everything in it.
