My religion......

As a young child, I attended church every Sunday and some Wednesday nights. I grew up in church and I was raised to believe that there was a God. I believe that there was a creator, who made everything. I know that there is a Bible, and I also know that there are other religious books. I believe in right from wrong, and I feel like the commandments are a set of laws that are set forth for people to abide. I believe that if I live a good life and ask for forgiveness of my sins, then I will go to Heaven. I also believe that when you pray, you are sending a direct message to God.
There are a couple of things that I do not understand about religion. One of the questions that I have is: Why there are so many different beliefs about religion and who is correct? If everyone worships something different, then how does one person know that their belief is true? How are people supposed to know which religion to practice?
I feel as though religion was based on different people disagreeing with one another. There are several denominations within each type of religion and most religions are practiced in certain regions around the world. Evidently, this was the case because even in Christianity, there are different types, Baptist and Pentecostal, for example.
Another thing that I believe about religion is that it depends on where you grow up and what your parents believe. Obviously, your parents are going to teach you their beliefs and it is normal to obey your parents.
One area that is confusing when it comes to religion is what comes after death. Some religions believe in reincarnation, heaven and hell, and some do not believe in anything.
I am skeptical about religion because there are many hypocrites in the world who proclaim to be religious and do bad things. This is contradictory and I would rather someone not profess to be something that they are not.
My general beliefs in life are to obey my parents, do not harm others, make good decisions, forgive others, and basically live a good life. I believe if I do all of these things then I will have a happy life and eternity.
