In what way are they both as valid when describing the physical existence of something?
In all walks of life where its important that things are true we don't rely on faith or belief.
1 -- n what way are they both as valid when describing the physical existence of something?
That is where you are going astray. Talking about a physical, touch me, see me existence of God! but instead the word - something is used in place of the word - God!
2 - In all walks of life where its important that things are true we don't rely on faith or belief.
That statement in and of itself is not true! Implying that if you have to rely on faith or belief, then what ever you are relying on cannot possibly be true!!
As magnus stated above me -- In the way we are speaking about, the belief in God. Shouldn't it be unique? God is beyond our frame of reference. Thought is real. Emotion is real.
