I wouldn't call that belief theology (as I am a student on theology), that is just downright make-believe. Not gonna say dinosaurs are blatantly explained in detail when they lived etc in the bible but there is enough evidence both in the Bible (and ya know, in the ground) to prove that dinosaurs did exist. But a lot of people don't like to deal with not knowing all the answers (the Bible is vague on dinosaurs and doesn't go into too much details on them, usually just referring to them as either dragons, leviathan, or behemoth) and so people decide to just say they are fake.
Pretty much. Given that the Bible was largely written during the Bronze Age, let alone by a Mesopotamian society that rarely got the chance to self-govern, expecting it to feature a deep understanding of the prehistoric world beyond what they found by happenstance in rock formations, quarries, and mines is a bit of a stretch to say the least.

Harland Sanders is especially inspirational, but also instructive. He failed over and over again, then he succeeded. He went through over a dozen careers that were not restaurant based. Then he worked at a restaurant and his chicken became very popular though it took him 30 minutes to cook it. He spent 9 years tinkering with ways to cook it faster without impeding the quality. And he lived in his car for two years while pitching his chicken frying technique to 1010 restaurants. 1009 restaurants told him "no".
