Model airplanes fly quite well. But they really aren't often practical for anything. Same with Big Bang models.
The part that is being left out of Big Bang is the intelligence. Because of universal entropy, everything reduces in complexity. Whatever could produce the complexity of the intelligence of man, especially over billions of years of cause and effect, and cause an orderly universe at the same time, must have been intelligent way beyond understanding. Start applying intelligence to the Big Bang, and you will be getting close to what the Creator is like in some ways.
Of course, Big Bang is just theory. Cause and effect have been proven to exist.
Problem with people like you is that you see mystery in everything. You claim that complexity is a proof of God existence. Just because we don't yet know what caused a Big Bang, it does not mean God did it. It just means we don't know.
Your mindset is no different from an ancient goat herder who wrote the Bible. He also saw a mysterious, very complex world and explained it with God.
Just because something is complex or unknown does not mean God did it. It means just that it is complex and not fully understood.
Repeating your nonsense over and over again will not make it true. Sorry to disappoint you.
PS. Claiming that explosions of supernovas are caused and planned by intelligence is insulting both.
If you walk around with your buddy at the time Jesus was supposedly crucified, and talked on a walkie-talkie, you will be in New Testament and Quran.
There would churches all around worshiping BADecker and his holy spirit.
