You are mistaken dude.
After Buddha's passing, monks came together to make records of Buddha's teaching, the Dharma. Though it was later recorded on leaves but monks recites these teachings in the form of Sutras so to remind each other about His teachings as well as passing the Dharma on for generations. That's how chanting in Buddhism comes about.
If you ever read any Sutra at all, it is not uncommon to read about how Buddha has taught his disciples about the importance of taking vows and paying respect or even praying to various Buddhas in strengthening their resolves in achieving Arahan.
Buddha has recollected his past 500 lives and there were many instances whereby praying to various pass Buddhas and Bodhisattvas that helped him in his enlightenment path.
