Welcome, Growinggirl and Notreadytorun:
Great names, btw. Mr. Flipper just spoke words of wisdom. GG, when I was going through the same mental anquish that you are currently experiencing, I asked myself, "If the WT really is the truth, then what else would also have to be true?" IOO, what does it mean in the larger framework for the JWs to have the only "truth"?
Well, for one it means that virtually every avenue of known scientific knowledge is wrong. This includes the vast array of information gleaned from DNA, geology and fossils regarding the history of life on earth, the basic laws of physics governing radiometric decay, the astronomy revealing irregularities in the earth's orbit (causing the known pattern of ice ages), the analyses of ice core samples calibrated to other historical physical data such as volcanic eruptions. I could go on but I won't--Leolaia recently reposted a fantastic listing of science that would have be wrong if the literal flood were true and you should check that out.
So if all this science is flat-out, dead wrong, what does that mean? It means, for one, that we can't "know" anything based on our senses. We can't trust any particular picture of the physical reality governing the conditions of our existence--how life on this planet works--based on any tangible, quantifiable data, regardless of how much independent lines of evidence converge or how consistent such "laws" are over time. (Actually, it would mean that such "laws" ARENT consistent--the very same laws that the WT points to as evidence of a designer. IOO, if the WT's view of life is right, then all those supposedly consistent laws aren't consistent at all). "Knowledge" can't come through our physical senses. It's just not accurate. So where does that leave us?
Basically, it leaves us with no way of verifying reality. The WT claims that w/o the "Truth," we have no purpose in life, that we're twisting aimlessly in the wind. Well, w/o any way of verifying reality--even verifying the reality of Biblical prophecies, which necessarily means relying on some physical data or another--we're left twisting in an epistemological wind, at the mercy of anyone who says, "Believe me--I'm telling you the truth," whether that happens to be the WT or another Jim Jones.
Oh, this was way longer than I intended, but I hope it makes sense. Think about it. I sure have.
