IANS, you and a bacteria in a Petri dish have the same lack of abstract thinking ability.<quoted text>
Whatever your argument, level it at the god;
The chance arrangement of some assumed substance operating under some assumed laws into a god will not happen unless it was pointed in the right direction.
If your argument were valid, then this would perforce be more valid, since your argument assumes the existence of an infinitely more complex entity to explain a simpler one that it says is too complex to exist undesigned.
A god like yours is the least likely thing imaginable to exist uncreated. Literally. If you disagree, name something that would possibly be less likely to exist uncreated than an infinite, immortal, sentient, volitional, omniscient, omnipotent, and perfectly moral being.
And if one existed, why aren't there many? What else is sui generis? Not even the universe itself in a many-worlds or multiverse scenario.
Don't worry about how what brought you into existence came into existence. Especially if it can dump you down the sink. Establish a rapport with it, then it may tell you what it knows.
