I am very fortunate to live in a country where Christianity is allowed. You are correct. And sure, people in China or Africa (althougth there are now a good portion of Christians in these areas) may have a different belief than me, but that does not make their opinion valid.
I believe every word that Christ said. So yes, it is my opinion, but...
Great, and you are entitled to hold to whatever beliefs and opinions you wish. However, that is not how science works. Science looks at observed data and tries to explain how things got to be that way. It then comes up with an explanation for it. That explanation is tested to see if it is consistent with the observations. If it is, it becomes a theory. Good theories inevitably make predictions about things that haven't yet been observed. When more observations are made, either they are consistent with the predictions of the theory, in which case the theory is strengthened, or they are inconsistent, in which case the theory is modified or abandoned. An idea for which the primary evidence is "it says so in the Bible" or "look around and the work of God is obvious" may be absolutely true, but they are not science and should not be taught to students in a science class.
How did you get so lucky to be right, and they are so unfortunate to be wrong?
