I understand nothing is absolute but there has to be some level of commonsense. Unfortunately science does not teach commonsense.
Are you saying that scientists do not have common sense because they cannot agree upon something? You realize that great ideas often come about when scientists disagree with each other. Many different disciplines are riddled with scientists who disagreed with each other; thus causing one scientists to develop his own theory, and someone else then disagreed with him and built on his theory, etc.
Common sense has little to do with anything, though common sense is helpful. But really all that matters is EVIDENCE. What you can prove with EXPERIMENTATION. Do you expect a scientist to say, "Well, I am right because that's common sense?" Seriously? Other scientists would say, "Prove it."
Are you done? lol Seriously, and I am not being mean, but I feel like I am arguing with a 7th grader about the basic tenets of science. They teach this stuff in junior highschool. You really lack an understanding of anything that is science. When I was teaching my little cousin about science, we had a similar conversation. I had to explain similar things that I am explaining to you, i.e., the process of science, etc.
ps - I believe you meant to write some level of "CONSENSUS." Not, some level of "COMMON SENSE." The latter makes absolutely no sense.
