How many gods are there? Well, of course an atheist would say that number is zero, but there are those that worship a variety of deities, some, like in Hinduism, much older (depending on the scholarship) of either Judaism or of course Christianity. There are still practitioners of Zoroastrianism in the Middle East, which is over 3,000 years old. It seems that even in ancient Israel, the land of one god, in the 8th and 7th centuries BCE, people were still worshipping other gods, as have been found in archeological excavations and described in The Bible Unearthed.
