Science can't tell anybody anything. It is a sort of process of elimination and what is left is the truth. No message.

Science is the advancement of knowledge, as we learn we change. There are still a lot of unanswered questions out there and theories abound, but they are only theories. When I first began to read about the universe the books all said the universe was forever with no boundaries which at the time seemed impossible to me. I couldn't grasp the concept of forever and it seemed to be an impossibility to me. Now we know the universe is expanding. Theories will be changed and modified all for the sake of knowledge, I hope.

If you really take Einstein's statement at face value, he's simply saying that science, for all its warts, is the best shot we have at approximating an accurate view of reality. Science is simply the work product of the scientific method, which is a methodology for minimizing / compensating for the known weaknesses in human thinking. It is an attempt to avoid confirmation bias, as much as anything. As well as commitment bias -- science self-corrects when new info or understanding justify it. Theists frequently try to flip that, and say, "ah ha, see science changes its mind, it's not reliable". But this is a feature, not a bug.

A lot of the popular science press gives science a bad name by conflating association with cause. Some new association that's found makes for good headlines and effective click-bait. But it shouldn't be written up as if anything is actually proven by it. This is the source of comedy like the Onion headline, "FDA says eggs are OK for you to eat until next Tuesday".

Skepticism, rationalism, empiricism and the scientific method are indeed the most precious thing we have. Will it be enough to ensure the survival of our species in the end? I don't know, but I certainly don't think the failed epistemology of religious faith is going to do it.

I think that science is forever evolving we think we know something then some other piece of information comes along that doesn't seem to fit unless other bits are shifted around - I don't mean its happening all the time but new theories are proposed often, So in some ways I imagine that we are perpetually in the dark moving into the light As I am nothing like a scientist the only thoughts that I have are pretty personal my paternal grandmother died of diabetes only a month before insulin was discovered she had a shock in the war seeing a munitions factory blown sky high with many of her friends in it and developed the illness - Now we are pretty good at managing diabetes and probably getting better all the time - I don't know about all of the human race but I have hope that there are people clever enough to find solutions to all sorts of problems.
