Why do Catholics worship the saints since this not in the bible?

Catholics do not worship the saints. Worship is reserved for God alone. We honor, or venerate, the saints as wonderful role models and intercessors. When we honor the saints, we also honor their Creator. Much the same as when we honor a great painting, or scupture or piece of music, we honor the artist. Saints make much better role models than athletes, rock stars actors and actresses who seem to be worshiped by all-too-many people these days. That is not in The Bible either.
