I would say the reason there are so many denominations is that, frankly, man is a fallen creature, and we live in a fallen world, and men are sinners, and the church, even though it is God's called-out expression, it's made up of sinful creatures. And man, what does man like to do? We like to argue, and strive, and pride, and say, "I'm better than this person, and I'm better than that person."
There are doctrinal distinctions between many, and those are very important to them. Why are there so many? It's because we are fallen, and I can't say which one's the right one. What I would say though is, more important than denomination is, what does the bible say? And are you going, and are you involved with a bible believing and teaching church, a church that opens the word of God and teaches it and disciples, that adheres to the orthodox truth of the Christian faith?
