Why do I have a hard time accepting the idea of evolution? Because, there isn't sufficient enough proof in modern science for evolution to exist.
One large strike for me personally with the theory of evolution is that for decades we thought that man evolved from primates through the course of millions of years. We've thought for a long, long time that we were evolved from monkeys but, turns out we weren't. It has now been completely proven wrong in modern science. So, if that's not to be believed and bogus, what did we evolve from? Oh, that's right, nothing because evolution doesn't exist.
Humans and modern life were created by God about 6,000 years ago and while, we might have changed a little bit in appearance since then, all animals and humans look pretty much the same as we did 6,000 years ago. I don't believe that we are millions of years old.
Now, on the idea of Dinosaurs I have no idea. I don't believe that they're hundreds of millions of years old but, I have no idea whether they existed or not. It doesn't matter to me personally, dinosaurs are and were cool and It's cool to imagine Dinosaurs walking this planet at one point. It's cool to imagine velociraptor attacks (Who were my favorite dinosaurs as a kid) Whether or not they literally walked the earth is, irrelevant to me. And whether they were wiped by a volcano or by a comet both, are noah's ark like God made national disasters so I can buy the theory that God scrapped them and decided to make humans instead. But, in the long run It's just... kind of irrelevant to me. It's also cool to read Greek and Roman Mythology. That doesn't make Greek and Roman Mythology real. In fact, it isn't and was a very entertaining thought and concept 2,000 years ago.
