i think that all reasonable people believe something has to have existed that wasn't created. It is a bad argument to say we have to have been created because of our complexity.
It appears you choose or have been led to conclude that god exists and it the uncreated thing. I have been led to conclude that matter/energy is the uncreated thing. I do not wish to persuade someone that god doesn't exist. I wish to persuade someone from making a very bad logical argument.
