Science produced wonderful insights over the centuries. We know more today than we did 10, 100, or 1000 years ago. Are we done? Have we learned all there is to learn about the universe and time and life?
Of course not.
"Since we know we don’t know what we don’t know, why would we assume that what we do know is enough?"
Don’t "trust" the science. No legitimate scientist would ever say, "Trust me, I am a scientist." Instead, follow the science, because science is the best way we have for falsifying competing theories.
Follow science, not scientists. Scientists are humans and thus fallible and suceptible. Scientists themselves know this, and for this reason the scientific method features a process of verification known as peer-review. The community is less likely to be wrong than any one individual. Paradoxically, the greatest advances in science have occurred when an individual challenged the frontier of human knowledge in an unexpected way. Progress depends on the rogues.
Bottom line: Life is an experiment. Choose your questions carefully. When you see an answer, be skeptical and critically examine the investigator's motive, funding source, context, method, results, and conclusions. Have the results been peer reviewed and replicated? Some questions are better than others and some answers are deadly.
