Rather huge difference between drawing inferences based on other, similar applications as part of the evidence chain and saying "Oh gee, I don't know, so therefore god."
lol - as usual you've filled in the story with your own preconceived notions. i never said anything about god, only faith. faith is beleiving in something which you do not know for certain to be true (or un-true). putting faith in something happens to everyone on a day-today basis, including those who prescribe strongly to the scientific method.
If a marble falls down when I drop it out a window, I don't need to test every object imaginable to conclude everything heavier than air will also fall downward.
Kn.
lol again.
as per your example you do need to know that the item in question is heavier than air. this of course would require some sort of current or previous testing; whether that be of your own volition or someone else's. and as per your example, comparing an objects weight to that of air is making some sort of test or conclusion.
it's entertaining watching you stumble your way out of situations where you've possibly made a mistake that just so happens to fly in the face of the science and methodology you so highly tout (which is perfectly acceptable and a smart thing to do). but, spaghetti monster ever forbid that you may actually admit to making a mistake of some sorts though.
We don't know what our limits are, so to start something with the idea of being limited actually ends up limiting us.
