That's not what I'm saying at all! To quote Sir Isaac Newton:
I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.
Science accepts it will never know everything about the universe. Science also accepts that without evidence there is no knowledge, only guesses. Ghosts might exist, so might Bigfoot, Nessie, and David Icke. We need evidence to demonstrate it, though. The possibility is not enough to warrant belief, as a whole bunch of things could be possible - science is the system of weeding out the actual from the possible.
