Not having doubt - having certainty - is a dangerous and stupid position to take. Particularly since the universe does not change according to your convictions.
when enough evidence is on hand, we can eliminate doubts, and a strong conviction takes place. Thats not a stupid position at all. I don't see your point. Do you have any doubt, the sun will rise tomorrow ? Not ?
You should not ever eliminate doubt. Then sun is easily observed. The earth and its rotation is easily observed. We have evidence of this and as you point out, that grants us a degree of certainty. However, there are still uncertainties involved. Perhaps a gigantic meteor we have not detected, or a heretofore unknown phenomenon in the sun that makes it unstable or emit a deadly burst of microwaves. Nefarious elements of the Paki government hand over a nuke to islamic radicals triggering a nuclear war. Any of these could cause the sun to not rise for us in the morning, however certain we may feel.
We know things. But we should be humble about what we know and allow for reality to change our minds. In light of that spirit, certitude is a counterproductive emotion. I'm not talking about checking first principles before getting out of bed in the morning or brain in a jar scenarios. That is no way to live. I'm talking about knowing that what we know is a tenuous model that is subject to change.
You stand on even more tenuous ground. A god who hides beyond time and space, who leaves no footprints, who will not deign to be tested, who ambiguously answers prayers with "yes, no, wait". Your philosophysizing is nice, but unless (until) you can check it against reality, it should be taken as seriously as Sasquatch or Area 51 conspiracy theories.
So my point, young buck, is if you want to say you believe in god, that is your prerogative, unjustified as I find it. But to say you have certitude about it, well, then you have adopted an idiot's position. And frankly, it sounds as if the lady doth protest too much.
