Consider how much we can't explain right in front of our own eyes, and then consider the abstract, unknown of God. It's far too difficult.
So you invent fairy stories about a sky father.
God is as viable an answer as any. If someone can explain with evidence how we have this massive universe, and how it came from nothing apparently, I'm all ears.
If it's Faith to believe in God, what sort of faith does it take to believe that all of the mass in the Universe came a Big Bang that was the size of a pin head?
To the comment below, I await your evidence as well. An explanation regarding how the Big Bang Theory isn't just that, a theory with no practical evidence. Worse, it is in fact a form of Faith, just as my belief of anyone elses belief in God is Faith.
