Your suggestion that science should be defined by non-scientists is like suggesting that brain surgery be defined by pianists. If you want to get in on who defines science you'll have to become a scientist. And, for you, that'll take a lot more education to gain the credibility you lack in this discussion.
I bet pianists could make good brain surgeons. They'd have the fine motor skills necessary.
No, it is not. I do not have to know all the rules of football to know when the game is not being played right. I do not have to be a concert pianist to know when the pianist makes a mistake in his performance. I do know that science does not rule things out as "unscientific" simply because they are not yet known. Science defines itself as it moves on, despite narrow minds like yours.
