Science admits this routinely--approximately about as many times as scientists speak in public, as it is a fundamental notion of a scientist's education--yet the effect you predict does not seem to occur.
I hate to disagree with you, but I do not see the scientific community behaving as you describe.
What I see the scientific professionals circling the wagons against the perceived threat of creationism. They correctly denounce creationsim as a non-science. Yet they continue to tolerate those in their midst who bait the creationists by making non-scientific attacks on religion. (I am thinking of Dawkins and his ilk.)
How should scientists respond to creationists? By refusing to argue with them about how and why the earth was created.
When creationists say that God created the Earth ex nihilo in six 24-hour days, do not tell them they are wrong or stupid. Simply say that such a creation would be a miracle, and science does not deal in miracles.
You might add that many of the great scientists have been and are religious persons. They have had no difficulty reconciling religion and science because they recognize that the two serve different purposes. If you are a religious person yourself, you could also say something about how you find that science and religion both play roles in your life.
