When our TV is turned on, we can see the picture. When it's off, the signals are still there, but we can't see the picture. Does that mean it doesn't exist when the TV is off?
In the Bible, scientific knowledge is called "gnosis". True scientific knowledge must include things of a "spiritual" nature, in other words, things that are beyond the five senses of human perception. (See "Metaphysics") This knowledge has been suppressed and kept from the mainstream for thousands of years, for control and domination by the elite. They have brainwashed and conditioned people to reject outright what is beyond their perception as "science fiction". JW's are especially turned off to things like this because they view everything of this nature as "occult" and "sorcery". The truth is that once outside this 3-dimensional time/space continuum, we get the true meaning of what the Bible really means when it says, "with God, all things are possible."
For the real gist of what I'm trying to explain, google Plato's "Allegory of the Cave". I'm on firefox at the moment and can't post any links.
