Of course, because I have sufficient evidence to believe I have these organs.
Yes thoughts come from your brain. That has been sufficiently shown by science. You change the brain you change the person. You cannot have thoughts without a brain. Science has shown that if you change the brain you can change how the person acts, thinks etc.
Not all of it. Some of it has been verified by archaeology some has been refuted by archaeology. I don't know if the miracles really happened but i don't have enough evidence to show that they did.
Of course. because I have an overwhelming amount of evidence that they do.
If I wanted to I could provide you with sufficient evidence to that. You have not provided sufficient evidence that god exists.
You have a clever proposition.
You don't "really" want "proof" of Gods existance, but rather "Evidence" that must satisfy what you call "sufficient evidence".
You trust scientific evidences, when you have neither seen the scientist, know his ethics, or know of his man made and calibrated tools, gadgetry, specs, allowances and would guess it doubtful you have read the scientist own journals.
And If a scientist says your thoughts are only derived from your brain, and without seeing thoughts manifested, you trust that is sufficient evidence.
But yet, When Scripture notifies you of The Lord God, has created and made the World: a world you can See and Observe the Awe, Complexity, Magnitude, and the Abundance of Life.....it just isn't quite up to your standard of viable "evidence" to believe.
Personally I find the simplicity of a Forest of trees, without mans intervention, More reliable evidence of God, than a man dictating the thoughts only come from a brain.
And just to note, the thoughts of the Carnal mind and the thoughts of the heart, are taught in Scripture. [and have person experience with both].
Looks like your quest for "sufficient evidence", might be dashed.
For men who "choose" to not believe;
God blinds their minds and hardens their hearts.
Glory to God,
