I believe that the earth is very old and that dinos probably roamed the earth before Adam and Eve and the Garden were created, since animals were created before humans. I liked also my son's thoughts on it. He said after learning about where probably the Garden of Eden was on the earth, and that the dinosaurs were on different continents on earth that it's possible they lived outside the garden in these countries which were nowhere near the Garden, and they died off due to whatever phenomena before the Fall or the the Fall caused their demise. Since there were no human bones found along dinosaur bones, I think this is a reasonable perspective.
That seems to go along with what Old Earth Creationism advocates when saying that death/dying occurred outside of the Garden of Eden (including the Dinosaurs and their eventual extinction after living centuries before Adam/Eve came into view)...and that Adam/Eve were pushed out into the rest of the world when they sinned, originally being kept from what happened in the rest of nature.
There's a lot of to consider, however, when seeing the accounts of things that are essentially modern-day dinosaur relics...as well as accounts of dinosaurs in remote parts of the world still existing and ancient pictures of men/dinosaurs living together. It's not necessarily the Flintstones reality, but there've been many things that were thought to have died out and revealed to still be living among us. Perhaps its possible that certain creatures lived on and simply went underground.
With the possibility of certain creatures existing, some of it seems similar to when others used to tell stories of "man beasts" in Africa and others scoffed, until they realized what the creatures were/discovered gorillas. The same goes for a host of other creatures within
cryptozoology..as it concerns how a cryptid (from the Greek "κρύπτω" (krypto) meaning "hide") is a creature or plant whose existence has been suggested but that is unrecognized by a scientific consensus. Many things that were thought to be scientifically impossible later are deemed to be quite realistic when seeing how they were diagnosed. There was an excellent series on the issue that I'm an avid fan of, known as "
Lost Tapes" (
here or here to
Lost Tapes : Animal Planet ). From the accounts of creatures such as Big Foot, to the Yeti and many others.
In light of the numerous tales around the world of creatures such as Dragons, some say that perhaps those were dinosaurs who still alive. As it concerns their existence today, I would have no reasons to doubt that anymore than it'd be with other creatures that people once thought to not be real.....be it Giant Squids or even things like the ancient fish
coelacanth. The coelacanth is an interesting example, seeing that at one point people considered them to be extinct for a LONG time/ancient....and then when one was discovered in the early 1900's, they realized that the fish itself was actually a DEEP-Sea fish. When they realized where its environment was, they began to find more.
Many other creatures may be within this realm...be it with dragons or types of dinosaurs thought to be extinct. On Dinosaurs, although some feel that the creatures went extinct, I'm open to the fact that they could still be alive, with most dying out in the flood and others surviving still. There's still debate on whether the dinosaurs existed in this age or the age before the flood.
From what I can see, in my understanding, I think dinosaurs existed in the age prior to the Flood and after...but in the age after the Flood, the environment may've been radically different and too much for the dinosaurs to really handle---thus causing their extinction. For those believing in a Global Flood, be it with large local floods happening worldwide/collectively covering the Globe or with the entire planet being covered in water, there's a view that the Ice Age happened after the Flood and the Dinosaurs passed away. For a good article on such, one can go online and investigate the following:
For those who are of the mindset that Dinosaurs died off long before the Flood ever occurred...and that its not necessary to look for evidence of them in the Bible in order to believe that they existed, they seem to have some valid nuggets of truth as well. For reference:
