To make Creationism a science, you'd have to start with some experiments.
Have there ever been successful lab experiments demonstrating how a god creates life (let alone two different lifeforms)?
You need:
1. A lab without any life in it.
2. A big or mid-sized all-powerful god. (You can use a Greek or Roman god or a Semitic god, I don't care; please refrain from using Hindu or native American gods if possible to make the experiment easier to reproduce. Darwinists use fruit flies because they are easily obtained and well-understood. But I don't know much about Hindu gods.)
3. A way to observe the process of creation. You can use a camera and I will happily believe that you will refrain from using camera tricks. (A man dressed like Zeus comes in and blinks and in the next scene there are 20 fruit flies flying around his head. If that happens I will assume it was not a camera trick if you tell me it wasn't.)
I can probably help you with the lab (i.e. point you to a local university), but obtaining the god can be somewhat difficult. For me it would be, since I don't believe that Creationism is science. For someone who knows that Creationism is science, obtaining the necessary gods for casual experiments is probably as easy a task as obtaining fruit flies is for those scientists who see a difference between Creationism and science.
