Question: How do you know Henry VIII had 6 different wives? How do you know Julius Caesar was assassinated in March of 44 B.C.? How do you know King Tut reigned over Egypt for 9 years? How do you know Jesus was crucified? These facts, and more, are all known to us purely by the historical record.
Lacking a historical record, our knowledge of history is extremely limited. Even if we find a few artifacts and piece together a possible narrative, we can never really be sure if we're right. In a discussion about whether or not triceratops may be the same species as torosaurus, John Scanella said "palaeontologists are at a disadvantage because we can't go out into the field and observe a living triceratops grow up from a baby to an adult." (1) This is true. Where regular historians have the advantage of eyewitness testimony preserved in the form of various documents and artefacts, palaeontologists lack such records.
How, then, can Evolutionists cling so dogmatically to their narrative? Historians, armed with their wealth of documentation, still face many unsolved mysteries. Even the date of Jesus' birth is disputed, and the further back in history you go, the foggier the details get. Yet Evolutionists want us to believe there is no logical reason to dispute their story? There was a time they would freak out if grass was depicted in a dinosaur book! We now know, based on a well preserved dinosaur stomach, that their narrative was (once again) wrong.
Far better to rely on an infallible, divinely inspired historical record that consistently and reliably proves true than to trust a shakey narrative that refuses to yield to contrary evidence.
