What were the three religious practices one could find in Mecca before Muhammad's revelations?

There were several
religious practices in Mecca before Muhammed and the start of Islam. For example, some people
followed a polytheistic religion. Arab polytheism involved worshipping deities such as Hubal at
the Kaaba in Mecca. The Kaaba, a granite cube that is Islam's holiest site, was, in the time
before Muhammed, the location of hundreds of idols, according to some historians. 

In addition, various forms of Christianity were practiced in Mecca,
including Miaphysitism (which maintains that Jesus Christ, humanity, and God are one), and its
rival sect of Christianity, Nestorianism (which maintains that there is a separation between the
human and divine forms of Jesus Christ). Judaism was also practiced in the region, as Jews had
migrated to the area since the Roman era, as was Zoroastrianism, the religion practiced in Iran
before Islam.
