I'm not confused at all. You're making an argument that is illogical, and I'm just pointing it out to you. I explained why it's illogical clearly enough. If you can't grasp the logic, that's out of my control.
I don't know the religious people you're talking about, but I certainly don't think God created humans the way they are for some reason other than because that's how He wanted to do it. He created life in an unimaginable variety of forms, obviously He could create it however He chose.
Once again, you say it's not intelligently designed, just the best evolution can do, without offering a more intelligent design. You say God could have created humans to reproduce without sperm. Single cell and low level organisms reproduce without sperm. You're the one who has to argue that there's some advantage to sexual reproduction that caused evolution to "create?' and select for that trait. So non sexual reproduction isn't actually a better design?
I know you didn't answer what the origin of life is, that's why I asked. "Where does God come from" isn't a response to that question, it's avoiding the question. Implying that my explanation for the origin of life is wrong isn't a "gotcha" if when you don't have an explanation at all. Like I said, God exists outside the parameters of time and the physical universe, so it's not a coherent question. Origin implies a time and a place, God isn't confined by time and place so He doesn't need an origin.
Mutations? So random copying mistakes in DNA? Coincidental errors? If you make enough mutations to a DNA string you go from a single cell organism with 500 genes to a human with 20,000 genes?
Genetic code is incredibly complex, but let's say for the sake of argument that one specific trait, say a functional wing, could be simplified down to a deck of 52 playing cards in a specific order. Would the mechanism of action be a mutation or mutations shuffle the deck, then natural selection determines whether the changes are beneficial, and if they aren't the organism just dies, but if it did succeed in getting the correct order to code for a wing, that organism will survive and pass on the improvement? And if the first try is a failure it basically just keeps "shuffling the deck" with more mutations until the correct sequence is hit and progress happens?
There's only one God, the one described in the Bible. God didn't say things that are false. Whether you choose to believe what He said is up to you, I'm not the one you'll have to answer to for your choice.
