When it comes to origins science, science has been wrong before, which tells us that science isn't always right. Scientists can't duplicate the beginning of the universe and all that has happened in the past. Scientists used to accept that the universe had no beginning. Well guess what, it was found out that it did which ended up supporting religion, religion won over science.
Religion has also been wrong before. Actually, the majority of religious claims have been shown to be wrong at some point. The majority of religions in our history are dead, gone, "disproven" by the new religions. Science has only had 2-300 years to catch up on religions 5,000+ years history. Still, science has brought us cellphones, computers, medicine, food, cars, airplanes, and millions of other things (for instance Internet that you right now are ironically enjoying). Science has solved more thousands of times more problems than religion even have ever though of. Of course science is wrong sometimes, we're humans after all, but the benefit of the scientific process is that we fix the problems, not stick to them like blind bulldogs. Science requires evidence. If the evidence points in another direction, we change. Religion requires belief without evidence. When the evidence points in the other direction, religion does not change. I rather stick with the crowd that can admit wrong, than the crowd that never can admit any error.
Science changes because each theory tries to explain the facts the best way. Each time science is wrong, the new and corrected model/theory is more right than the old one. Being wrong in science doesn't mean that it changes everything, but that changes closer to the truth. The science we have today is closer to the truth about nature than the science we had 100 years ago.
