Is it illogical to believe that suddenly there is a complex supernatural Creator who had no origin; He was always there?

We can drive ourselves crazy looking for the answers!  Sometimes we just have to let it be.. let it be.. let it be.. yea let it be, there will be an answer, let it be. :)

Philosophers and theologians have debated this for centuries, and nobody has ever come up with a definitive answer. It boils down to what you want to believe. If someone wants to believe that an all powerful creator who has been around for all time created the universe then good for you, but it still leaves a lot of unanswered questions. If you prefer to believe in the laws of physics then good for you, but it still leaves a lot of unanswered questions.

To answer your question,yes, it is. Why? because it defies logic. If our method of creation was meant for us to know, we would've known it by now.

Hatter--"Meant for us to know" by whom?

MackTheKnife--It boils down to whether you want to scour the heavens, or if you want to evaluate the current research in theoretical physics and cosmology. One relies on revelation and the other on patterns of observed phenomena. 

Asha--I think answers from divine revelation are the preferred choice of lazy thinkers. It is like Adam saying to Eve "let it be." I seek knowledge beyond the mythological writings of the Dark Ages and the earlier Bronze Age.

to worship, honor and glorify our magnificent and merciful God and Savior Jesus Christ.

Logic can only take us so far. Is it logical to believe that before the "Big Bang"or whatever cosmological origin one believes in, that nothing existed? Logic begs the question of cause and effect, whether you bring God into it or not.

If the universe can be eternal (without beginning) in all its complexity, why not God? Is an all-knowing God harder to explain than an uncreated universe in which there are billions of stars, where a microscopic cell in our bodies contains an entire factory of organelles and chemicals that perfectly replicate proteins and send them exactly where they are needed?

Every step science takes reveals deeper mysteries and greater complications. To me, there is only one "logical" place that path can lead

P,  as usual you ask many questions under one heading.  However,  Complex comes from simple if you are talking about things that evolve.  God does not evolve.  God is eternal; he was not created and He does not evolve.  He is constant.  Forever,  He will be too complex to completely understand. 

It is not LOGICAL from the human perspective for God to love a person who disobeys and questions Him at every turn,  but He does. 

We look to particle physics to determine how things work,  not where they came from. 

God is defined as the first cause or "uncaused cause". There is either an infinite regression of causes or there is a first cause (or set of causes). I would consider the infinite regression more complex. Now, if one has concluded that there is a single first cause, one could still apply Occam's razor when reasoning about its characteristics.
