Conversely, what you are implying is that you believe dinosaurs actually existed within the last ten thousand years. Tyrannasaurus Rex, triceratops, pterodactils, etc. Now, I think you need to tell the truth to the good people on this forum and let us know exactly when you think dinosaurs existed. My guess is 60 to 150 million years ago. Now it's your turn.
Since neither of us was there, we must base our opinions on what we consider the best authority. If no credible authority exists, then it is foolishness to be dogmatic on any possible explanation.
I must, as an issue of faith and to be consistant with what I know to be true, have considered the Bible as the absolute authority on this topic. Fortunately, the evidence supports the Bible's claim. According to lineage, and the reasonable assumption that the lineages are consecutive, Usher's date puts the age of the earth at under seven thousand years. This of course makes 60 to 150 million years ago impossible. What evolutionists call evidence of billions of years of uniform environment, Creationists call evidence of a catastrophic global flood that we are told is only a several thousand years old.
The empirical evidence we have today that "dinosaurs" and man walked together is found in places like GlenRose Texas, granted the human footprints are large and are indicative of a very tall (or giant) people. No problem, the Antediluvians talked about a race of giants we call the Nephilim. (Imagine the NY Giants changing their name...heh,heh,heh). There is also the chinese legends and the south american pottery, and north american and european cave art that features in convincing detail certain large creatures evolutionists would label "dinosaurs" if they were only dead 60 million years previously. Job was reminded of a great Behemoth, that theistic evolutionists have tried to pass off as a hippopotamus (despite the tail described as a mighty cedar, and the "tightly knit" thighs ). John Allen Watson, a geologist here in Austin wrote a paper titled "Behemoth" that describes in detail why this creature was probably a sauropod. According to Dr Look, French Congo tribes today still talk about (and apparently worship) a sauropod like creature that lives in the waters and occasionally capsizes their canoes (with men in it) with its "trunk".
So I base my opinions on Scripture, and also on the empirical observations made by archaeologists, and the numerous claims of disparate cultures around the world to co-exist with these "dinosaurs". There is even certain European lore of "dragon slayers" as recent as the Medieval ages. Nessie within the confines of Loch Ness? Is absence of evidence evidence of absense?
