THE "BIG BANG" PRODUCES ORDER??

Modern science theory says the universe as we know it was produced by a "Big Bang."

But is this a reasonable theory?

Can this theory be tested?

Consider:
-Have you ever taken a cherry bomb or fire cracker and lit it off?
-What resulted? Order? .... or chaos?

Consider:
-A car engine.
-There is an explosion that produces power which ultimately drives the wheels moving the car.
-But what is required for that explosion to be productive?
-Must it not be "contained" by some very sophisticated design (the cylinder, pistons, crank arms, wrist pins, etc.)?
-Is it not engineered by a person understanding, at a minimum, thermo dynamics and mechanical engineering?
-In other words: there had to be some intelligent design behind the controlled explosion that produces an "ordered result" instead of an explosion that produces chaos.

Q. If you now apply that to the origin of the universe, does it not seem logical that there must have been some intelligent design behind, even a "big bang" that would be required to produce all the order that we see around us today?

Q. So what was that "intelligent design" behind the supposed "big bang"?

-It had to be something far more orderly and intelligent than "liting off a big cherry bomb"!

-Ohh, by the way....who or what lit the cherry bomb to start with ?
