Re: Prayer Doesn't Heal the Sick. Medicine Does.

So, a couple days ago, I made a journal expressing how I feel about people believing that prayer heals the sick and don't attribute anything to medicine or doctors. I'm bringing this journal up again because of a conversation that I had with my mom. We were talking about how some people refuse to get vaccinations, and, in passing, I made the remark: "Yeah. It's just as crazy as the people who refuse to get medical help for a disease because they think that prayer alone will help them." Now, thankfully, my mom agreed that people need to get medical help in order to stay alive and well, but she also said, "I believe that God gave doctors the knowledge that they need to heal people." I replied, "But they have to go to school in order to obtain that knowledge," and she said, "Who do you think gave them that intelligence?" Now this is where the conversation ended-- not because I had nothing to say, but before I could say anything, my mom changed the subject, but at that point, I was already thinking to myself, If that's true, then why do we still have gaps in our knowledge? Why do we still not know everything about medicine, like how to cure cancer, or how to handle the Ebola outbreak in Africa? When humans first appeared as a product of millions of years of evolution, we didn't know jacksh*t about medicine. We just had to rely on our instinct, and it took millions of years for us (as a species) to obtain the knowledge that we currently have. If God really gave us that knowledge, then why are there so many things we have to conduct research on and figure out for ourselves, while having to watch countless innocent people die while trying to find answers? Also, there are signs of intelligence and the ability to learn in other animals besides humans. It's just not as advanced on the evolutionary spectrum as human intelligence. 
Now that the conversation is over, I'm really wishing that I had replied to my mom's final question of that subject matter with "nobody" and finally came out as an atheist. But... it's not that simple. Sigh.
