No scientist is a creationist? What about Newton?
Where did Newton insert supernatural mechanisms into his scientific explanations?
Why do atheists think they get to decide who is a scientist and who isn't?
The scientific community decides what is and is not science. This community is made up of people from every walk of life including christians, muslims, hindus, and atheists. This isn't an atheist conspiracy. The scientific community is full of theists of every stripe.
If there are no creationist scientists, then who created scientists?
There are scientists who are creationists. However, I have yet to see a scientist who has successfully used creationism to do science. There are creationists who are more than capable of keeping their creationist beliefs out of their science.
As to who created scientists, that would be their parents. You have learned about the birds and the bees, have you not?
