There is some uncertainty in the scientific dating process. Unfortunately, science can be corrupted as much as religion. I think a lot of people want to substitute science for some mythological religion with all the brances of science making one or another lesser god where people can go for answers and expect 'true knowledge'.
Unfortunately, science was created by humans (which some can say the same of religion) and is intertwined with money and politics (again some can say the same of religion). So, do we believe science or religion?
I think part of the answer is how you were brought up and how much you know about science. Newton, who was a closet alchemist, was more of a true scientist in his belief and trust in science. You have to trust in science, or it doesn't make any sense. By that I mean some things you must take on faith. A faith in science.
Science is continually trying to answer questions about the cosmos, our past, who we are, where we came from, how we can be saved... all questions that religion typically answers. And science, as a discipline, is distorted in the process and made to be something it is not.
The belief that man came from apes based on the theory of evolution is not conclusive and is a misuse of science. Offering the rhetoric of evolution is the goal of science, but making it appear conclusive is not. We believe there are other planets like ours in the cosmos because we exist. There is no evidence. Similarly, we have not found a human being before a certain time based on carbon14 dating so we say they didn't exist. Where is the consistency in that thinking?
Some can argue that all that happened before mankind became 'sentient' is not described in the bible and that modern humans are the result of god. Dinosaurs, like many other things, aren't mentioned because they are not relevent. However, I think ministers and defenders of the bible who think the earth is 11,000 years old are mistaken and maybe need more faith in science.
