Help on a scholarship essay!!?

well it says describe an incident or situation in your life which piqued your intellectual curiosity... (im guesing pretty much means something that made me want to find out more information about...) I was thinking about comparing astrology with religion because this school is a private college affliated with catholic religion. I'm not exactly sure how to state it as a SITUATION instead of just a theory.... Or if you have any ideas please help! Thank-you!
