I have a lifelong interest in science and the philosophy of science and I also studied it at uni, and all the points you bring up can only be answered superficially in the context of a steemit discussion unfortunately!

But roughly:

The whole first paragraph relates to how science is applied. If people twist science to fit their agendas, that's not the fault of the scientific method per se. When it comes to the method itself, it's the best method humans ever came up with regarding discovering the truth, a truth that can be publicly shared and demonstrated, instead of requiring 'faith'. Do you know of any better method? Something better to replace science with, that won't have all those issues you've brought up?

Also, about the 'schooling to become a priest' point - that seems to me to be a random superficial resemblance. I mean, if I send you papers from a discipline such as mathematics, will you be able to understand them? Of course you need to train to become a 'priest'. It's the same for football: you need to train. Do you think football is a religion? Well, I walked right into that one! But you get what I mean! You wouldn't trust me to build your house, or it would fall on your head! That doesn't make architecture a religion, nor the architect a priest. It just makes it a skill.

The things you say in your second paragraph, science not only acknowledges, but has actually discovered! Otherwise you wouldn't be mentioning it. And there's much else besides. Only recently I was discussing here on steemit the effect the time a person eats has on his behavior and decisions. This study shows how having lunch influences judges in their decisions in courts of law, that are supposed to be objective. Daniel Kahneman, who is responsible for this and many studies of this kind, showing human fallibility, has received the Nobel Prize for his work. Science awards this kind of work. Science has no interest in hiding these stuff, only in exposing it. Why? Because the moment science stops working, it loses its currency. The only reason you can be here on steemit is because of science. Without these practical results in every area of life, science loses its foothold, and religion comes back with a vengeance! Science either continues to show practical benefit, or it dies.

I have no doubt that you can comb the history of science and demonstrate many of the things you talked about, but I'm afraid you will be doing so at the expense of the big picture. I.e. you will be concentrating on the errors, rather than the successes of science. I mean, look around you! To me, it's emphatically evident that science is more factual than any religion. I would definitely choose a doctor over a shaman.

Btw if my style comes off as in any way aggressive, I apologize! It's just how I talk.

I'm off to bed now! :P
