"Science can only really explain what is observable in the natural world. It does not deal with the supernatural"
Ah...not quite. Science does deal with fantasy personality, schizophrenia, the provable lack of ESP, lack of effectiveness of prayer, etc.
"therefore whatever is natural, is theoretically, truth."
Yeah, I would have left "theoretically" out, but ok. I am with you.
"But also, whatever is supernatural cannot be denied by science because it is outside the bounds of what science can measure"
Mentioned by somebody before. Can you spell Occams razor? So...science cannot deny that on the planet Neptune, there are 1000 mile tall pink elephants dancing the watusi to the tune of "rock the casbah". This is where logic and reason come to play. Although this is a valid argument, it is not a sound argument. I contend this on prima facia evidence alone.
"Faith is, therefore, above science"
Read my last paragraph above, and understand why I contend that "faith is, therefore, BELOW science".
