Why do Rman Catholic people believe you must do all this religious sacraments in order to make to heaven?

Now I was raised Catholic so now I am an ex- Catholic. I still can not understand why Catholic believers think they must get babies baptism, first communion, confirmation get all these religious sacraments in order to make it to heaven when never read the Bible. ? Must Catholic do not even have a close relationship with God ๐Ÿ™ when they made all these covenets. Why?
