"You made the following statement: 'Atheists represent a group with the evil and ignorant agenda of ultimate denial.
The fatuous pretense that everything made itself from nothing takes far more faith than Christianity.' Please explain the Big Bang."

It's a nonsense theory. There's your explanation.

"According to whom?"

People with functioning brains.

"Study of the Big Bang takes someone with great knowledge in astronomy and physics."

And acceptance of it takes someone who refuses to use common sense and logic.

"On the contrary. Said scientists have studied the Big Bang for years and have reached a logical conclusion based on the evidence they have gathered. Have you studied the Big Bang?"

To the contrary, there is NO evidence for Big Bang to allow anyone to come to any "logical conclusion" that is ever occurred.

Please explain the cosmic microwave background radiation."

It is something that in no way is any kind of evidence for the ridiculous "Big Bang" theory.
