Who Created God?

A  father was reading a story to his young son about cosmetology and likened the earth  to a ball sitting on the back of a huge turtle. The young boy replied “but dad who made the turtle and what is holding up the turtle” “The father replied it’s, “turtles all the way down.” To deny a first cause in the end is to deny reason and the principle of cause-and-effect which simply says that everything must have a cause that is equal or greater than itself.  If I find a complex computer in the wilderness I would automatically look for an intelligent life form that created it. I could say that it always existed but it seems that that would be begging the question and surely wouldn’t answer the need for a cause or the ground for understanding the computer. Young children may ask, “who made the turtle”  grown men do not.
