- Biblical references to behemoth and leviathan, assumed to be actual creatures and dinosaurs,
- Literary references to dragons (said dragons assumed to be dinosaurs),
- Cave paintings believed to depict dinosaurs contemporary with the humans who drew them, and
- Human and dinosaur footprints in the same rock.
- The plants and animals found with dinosaurs are not the same plants and animals found with humans (not even close). No modern plants or animals have been found with dinosaurs, for example, and no plants or animals found with dinosaurs have been found with human remains.
- Dinosaurs and humans are not found in the same strata. For example, in Kansas, dinosaurs can be found in the remains of a shallow sea, while people are found in the remains of a vast plain. Note that the biblical references to behemoth and leviathan refer to these creatures as being alive in the author’s lifetime, so they all could not have died off pre-flood.
- Unlike other extinct creatures that humans interacted with (the mammoth, for instance), there are no artifacts demonstrating interaction. We have found mammoth bones scored by spears, charred bones of mammoths in trash heaps, carved mammoth tusks, etc. There have been no such finds involving dinosaurs.
- Ancients ran across dinosaur fossils as well, and tales of large creatures could easily have come from these bones – just as our dinosaur stories in our popular culture have. Furher, dragons don't actually look or act much like dinosaurs (except that they are both large).
- The Bible's references to dinosaurs? There isn't any. The Bible refers to creatures known to the readers - and we have no evidence that dinosaurs lived with people (remember the evidence for human-mammoth interaction - and this is in pre-literate, pre-historic cultures; by the times of the Bible, we are dealing with literate cultures where we would have every reason to expect dinosaurs to show up, just like bears, lions, locusts and a host of other clearly identifiable animals do, in paintings, in literature, in "scientific" treatises, etc.).
- The claims of human footprints found in the same rock with dinosaurs have turned out to be made in error. Even a quick Google of the subject puts the claims to rest (sure, some people still support the idea, but there is no substantive evidence - none at all).
There is a big difference between explaining how something could be true, and actually looking at the evidence we have, and concluding it actually IS true. You can believe that humans and dinosaurs lived at the same time only if you look at a small sub-section of the evidence, and present that sub-section in the best possible light. Look at all the evidence, and subject that evidence to critical thinking, and you realize that people and dinosaurs never met.
