The main reason I'm an atheist

-- Is the mind-boggling size of our known universe.  
I just saw a great video that demonstrates the actual distances within our own solar system in layperson's terms.  It's on Science.Mic if you're interested: 
Mark Rober - Size of the Solar System

In the video, Rober also briefly talks about the Hubble Deep Field images.  (Described by Bryan Braun as "The Most Important Image Ever Taken".) http://www.bryanbraun.com/2011/01/23/the...ever-taken "There are an estimated 10,000 galaxies shown in the image. Each galaxy contains millions of stars. All this was found in a dark spot in the sky behind the eye of a needle. That's equal to roughly one thirteen-millionth of the total area of the sky."

For me, just the distance between the Earth and Saturn is too far to imagine.  (746 million miles/1.2 billion kilometers at the closest point.  Earth: Circumference: 24,901 mi / Distance from Sun: 92.96 million miles)  From Saturn, the Earth is, as Carl Sagan put it, a "pale blue dot".  And yet, people are still killing each other over which middle eastern tribe, squatting on an 8000 square mile plot of arid land, has the right imaginary friend. 

Forget the concept of a being that created the universe, or even the solar system for a moment. Shrink the "god concept" down to a being capable of LOCATING this pale blue dot, and deciding to start or seed LIFE on it. This being would be so far beyond our comprehension - - an intelligence gap greater than human vs. a paramecium.  But most people's concept of god is of a sky-daddy who knows every thought, hears every prayer, and cares about every action. They also believe sky-daddy wants every human to believe (but can't convince 8 billion humans what they're supposed to call him) and will punish them for eternity if they choose the wrong name.
