Take for example someone giving you a glass that looks like water. There are however quite a few different liquids out there that look like water. If someone came along and said to you before you drink it, this is not water. He could have a good point. How you'd go about determining that are just simple tests, we've evolved them over time. There are many ways one could determine if indeed it is water that is contained in the glass. One could taste to see if it tastes like water, if it freezes like water, if it evaporates like water, when you shake the glass does it behave like water, determine the amount hydrogen per oxygen present / molecule ect... However if when testing it tastes odd, doesn't freeze, evaporates rather quickly, the hydrogen count is off ect... you start looking at that glass of liquid as something other than water. One thing for sure, the more tests you apply and it comes positive for "like water" can you be sure this liquid is water. It's simple, it's human like behavior and we all do it from the simple ones to the more complex ones all the time. The "good, hopeful, high oxytocin feeling" is something everyone gets from praying. May it be muslims, catholics, latter day saints, protestants, jews, hindus ect... The power of prayer is real. It releases, in some cases massive amounts of oxytocin also named the love hormone in the brain. You can also trigger it by hugging someone, try it you will see, the harder (closer) and the more intimate you are with the person you are hugging the more you release! My whole point is prayer is just one of those tests. Even if the Book of Mormon comes out positive through this test, so does Bible (christians) so does the Koran (muslims) so does the Talmud (jews) and I could list any number of books that people have prayed about and thought it to be true. My response is simple. Just because it looks, smells, and behaves like the liquid in a glass of water doesn't make it water. Just one test doesn't mean the Book of Mormon is true. Prayer is known to make you feel good, and that will be true for any book you are praying about. Shake the glass! Freeze the liquid! Taste it!
