Actually, I think many Buddhists and Hindus feel comfortable with the notion of a flawed creator.
Many other Buddhists (Zen in particular) have no use for a deity concept whatsoever. In fact, many religion scholars consider the roots of Buddhism to be an atheist philosophy, rather than a religion per se. Some branches of Buddhism, in particular those that are heavily influenced by Hinduism (like Tibetan Buddhism), have since embraced the idea of a divine creator. Other branches - those that are more influenced by the Chinese Taoism - have never done that.

Here's an excellent book. The World's Religions, by Huston Smith.

As a non-religious person, I was very surprised to enjoy this book as much as I did. I still refer to it quite often.
