God is one, and no some-other-thing is like Him.
In God you must believe or not believing is not looking for proves.
If you want to see God or expoct from someone else to admit it, you just play with the religion.
For a bagger, Bread is God, For a ignorant, Knowledge is god.
For a baby, mother is God and for a seeker, grace is god.
If we define God as formless, dimensionless, propertyless, odourless, colourless object, then we will never be able to "see" it. Only some self styled people can claim that they can experience God and fool the common people.
But if we define that this universe itself is a manifestation of God, we will be able to see God everywhere.
