Is the Tao god

Many Taoists do worship Gods, most of them being Chinese folk Gods. It's important to understand that in China, people do not simply practice one religion but practice several intermingled together. Honestly to get a satisfactory answer you may have to discern which tradition of Taoism you speak of, because practiced Taoism has many different flavors. Looking at the Tao te Ching itself, there isn't necessarily a 'God' that is worshiped. Tao itself can be said to be similar to a God, but there's a few key differences from your standard deity including an impersonality in regards to the human race, with humans just another facet of existence and not anything held up on a pedestal. It's more of the underlying reality and patterns of nature than it is any type of personification humans can relate to like most deities tend to be.
