Man made religion is complex because man made religion is a false way of life with bogus concepts about life and doing things better, they make up their own rules. Man made religion is part of the reason why people refuse to follow Jesus Christ. Most people see going to church as religion because some churches have religious regulations to it. So when people talk about the Lord Jesus Christ people are automatically discouraged because they automatically think of all these "rules and regulations" they have to follow. Look at how the catholic church operates. You cannot receive communion until you do all these classes and get accepted into the church and etc. However that is not even biblical!
