From what you are saying, it appears that you think that the mention of the possibility of a creator during high school would turn more kids away from science. I don't want to put words in your mouth. Is that your point? I would think that the opposite would be true.
Unfortunately, many of our students are directed into other fields by the quality of the educational process, and so become lawyers, economists, or sociologists.
(Fortunately, many non-US scientists are helping to fill the educational gap.)
Perhaps it would be more clear if I rephrased my comment; we can turn kids off to science at any point in the educational process, resulting in more lawyers, economists, or sociologists (which I don't think we need; let me also add "educators" to that list).
Clearly the mention of a creator is not what would turn kids away from science. But, many of the creationist posters on these very threads want to destroy any part of science dealing with evolution, and in many cases they attack the very methods of science to do so.
Attacking the methods and goals of science is not a productive method for raising young people to be scientists, and that is what I would not want to see in schools.
