I wasn't even asking about creationists per say. You can be a scientist and believe in a creator, that's not the question. If you submit a paper I assume there are editors it has to pass through. If it's not approved, then how do you get published?
You modify the paper according to the recommendations or send it to another journal (there are many). But the editors want to publish articles that have new and bold ideas that are supported by the evidence. That is what gives journals their reputation.
So, for example, when Einstein wrote his articles for relativity, it was a bold set of new ideas that were originally taken skeptically by many people (as they should have been). The evidence showed them to be correct.
But, make no mistake, the process of getting a paper accepted is grueling. This is true for anyone. You can't simply spout well-known views: they aren't new. You can't simply speculate about some crazy idea: you need to find evidence and support your views. You have to understand how your idea relates to the overall discussion about a topic *and be able to refute other views*. You can't simply state that the standard view makes no sense: you have to provide actual evidence that refutes it.
if you can't do this, you don't get published. But that isn't any different for creationists than it is for anyone else who needs to publish to keep their job. Being a research scientists is NOT an easy job.
it is not at all uncommon for a scientist to work on a paper for a year, send it off, having it rejected, send it to another journal, which requires edits, and only getting the paper published after a couple of years have passed. This has happened to me in mathematics.
Note: it is not uncommon either for positions to require 2 or 3 publications per year. You figure out what that means.
