Simple. God doesn't exist at all, and the Bible is a work of fiction.
Here's the real question you should be considering...
If God is all-powerful, he wants us to worship him, he wants us to follow his commandments, and do as he says...why does he make it so ****ing confusing? Why is there even a need to have this debate?
You want to worship the correct god, don't you? You're a decent god-fearing person, right? Well, so are Jehovah's Witnesses. God has to be capable of clearing up all this confusion, can't he? So why would God allow you to be confused by the wording of his book?
Why even put it in a book? Why not just appear before you and tell you what's true and what's not? Why leave it up for debate when there is so much at stake?
There are literally thousands of different religions that have existed over thousands of years all worshiping slightly different versions of a God. If God was actually real he could solve this debate in an instant.
Yet he chooses to allow his people to fight and kill each other because each one of them is 1000% convinced that they are the chosen ones who actually have the correct answer. When in reality 99.9% of them are wrong.
Isn't the most logical conclusion that God doesn't exist at all? That's why he can't and won't solve this problem, he's not real.
Ask yourself, if you loved the world so much that you'd give your only child would you allow such confusion? Would you let people fight, kill all in the name of false gods all because you refuse to set the record straight for them?
How does any of that make sense to you?
