Yes, it is real and one of the most successful theories in all science.
I offer the following challenge to Creationists. So far, none have accepted.
Let us be pragmatic about this: Let us NOT argue about the truth of our respective theories of how biology works. Rather let us apply Matthew Chapter 7, Verse 16. Which theory works best?

Your turn, what have Creationists done that matches that impressive record of achievement?
Thousands of patents in various forms of biotechnology outlining useful or potentially useful inventions.
