Let's say I wrote a good article on my new blog. then I submit the article to another article site for promotion say ezinearticles.com. In this case, Will google think that my site copied the article from them and view my filter my blog out? (apparently, comparing to my new blog, they have the authority).

If yes, is it safer if I wait until Google index my blog post first, then submit to ezinearticles.com. Would this be a solution?
