''but enough to realize that not all thoughts are my own.'' Again, you might think you realize those thoughts are not your own but how do you know? Is there a way to prove it or test it? Of course not, it's just your brain, as usual. That's why mentally ill people think they can fly or someone is telling them things.
Actually, there is. For decades, now, doctors who opened up a person's skull, and sent a little jolt of electricity through sections of the brain, induced thoughts in a patient that weren't exactly his. In similar way all of cause and effect induces thoughts in all of us.
The question should be, Are any of my thoughts mine?
''inducing'' thoughts by stimulating a brain doesn't mean the thoughts are from a god or another being, that's not even close of being evidence of that mate.
