Science is inherently atheistic

[Angrboda]

Well, I don't agree with you there, or your characterization of the value of your prior citation.  But let's take a different tack to see if we can add light on the subject.  How would you go about proving that gravity has a natural rather than a supernatural cause?

(As a parenthetical, I'll note that your example of Newtonian gravity says nothing about the underlying metaphysics of gravity.  Did they err, and simply omit the necessary metaphysical qualifications?)

It's fine if you want to look at it metaphysically and I'm not knocking you for doing so.  I don't agree with everybody, and likewise I don't expect everybody to agree with me.  

If you can provide information from some accredited university or scientific organization that both adheres to and explains your belief on gravity, then I'll be more than happy to considerate it.  If not, I'm just going to bow out of this conversation here, or we'll just keep going round-n-round about natural law vs metaphysics, and to me that just ends up being unproductive

You didn't answer the question. How would you go about proving that gravity has a natural rather than a supernatural cause?
