People spend their entire lives looking for God's Existence and Presence, Many claim to know Him/Her/It... While many claim that He/She/It does not exist...
The way this device you are reading this blog on, or the clothes you wear, could not have appeared out of thin air, like wise its difficult to say/prove that anything/something/everything in this universe has appeared out of nothing!!! Thus the possibility of the Existence of God is more than the possibility of God not existing.
But the Honest Truth is No one can Comprehend anything so complicated and vast with a "Cup Full Of Brains"
