I have some problems with Mormonism:
…
I am not anti-Mormon. Mormons are good people. Many of them are dedicated to their faith and donate money to the church, which goes toward helping others. But they have some beliefs that I do not think are supported in reality…
Stephe1987,
Your questions have been answered many times during conversations on various threads, and are also answered in other places on the internet.
But since you are seeking to be an educated person, that shows you are familiar with test-taking, I assume. You would also be familiar with the idea that a teacher prepares the test for the students…
Perhaps you are familiar with the idea of “free will and choice”.
The Mormons believe this life is a test of the exercise of “free will and choice”, and that God administers this test perfectly–absolutely perfectly, with no hitches, no cheating, no chance that something can go wrong in the outcome of the test, or someone can be living the commandments for the wrong motives and never be “found out”. It will eventually be “found out” if they are living the commandments for the wrong motives. (One can see all sorts of motives in how people look at the Mormon church, as evidenced in this thread.)
The commandment to practice plural marriage, given for a period of time and then withdrawn, was a test of faith and a test of motives. It was a tough test of faith for several people, as would be expected by people in our shoes today–it was against everything they had all been taught. Then there was another test of faith for some people when the practice was removed, the test being whether they were willing to follow the prophet of God on the earth or not.
As far as God’s test of people’s faith and motives for keeping the commandments, since He is the perfect test-Giver then we all can rest assured that He is giving the perfect test as to the “free will and choice” exercise of heartfelt motives by every person on earth who has ever lived.
If you think about the exercise of “free will and choice”, and then think about whether a set-up where the religion of choice for people was obligatory based on historical “facts” or archeology or “traditions” or so forth, but then allow yourself to think that God can indeed create the conditions wherein the test of this life will have been a perfect test of faith and motives, then perhaps some of your questions will have a less clear answer in your thinking than the answer you seem to have that “some beliefs are not supported in reality.”
If beliefs are all supported in “reality”, meaning the Holy Ghost no longer needs to be involved in testifying to the soul of the person that the reality of the life and atonement of Jesus Christ is the central message of salvation and that repentance through the atonement is absolutely what this life is all about, leading to peace among men and personal peace for every soul who repents with pure motives–then beliefs can go in many directions because there will always be religious beliefs that for one person’s “reality” another person will totally disagree.
The Old Testament shows over and over that the house of Israel was warned and warned again about following the “false gods” of their neighboring peoples. Then they were told by God that they had done exactly that. Yet they had “proofs” in their history and in what they carried with them (the ark of the covenant, for example). What they lacked was that they were more interested in following the traditions that became so ingrained that the Pharisees had an automatic response to someone teaching about repentance coming among them–whether John the Baptist or Christ Himself. They were insistent that their religious traditions could not possibly be wrong.
“Not possibly be wrong” removes the “perfect test” situation, because then people are acting out of obligation rather than out of the deepest motives, desires, and faith that are in their heart and reflected in the choices they make during the course of their lives.
Again, God is the absolutely perfect test-Giver–and here we are. Happy test-taking to you!
Peace, and happy studying.

Have a good day.
