You mean Personal Belief?
know enough? you already admitted not doing it yourself, reading it from someone else and then you will say you know enough?
When you believed about Dinosaurs existing millions of years ago, coming from a person who based his principles on Physical Scientific Evidence - Which part or your OWN knowledge or your ' i do know enough' to support that your belief is True? Did you DO Something else by yourself to support your belief? OR IS all your proof Not yours and you Just copied it from Someone?
