Quotes

I'm not familiar enough with Hinduism to comment too strongly, but it's my understanding that while Brahma is the god of creation, he didn't create Vishnu and Shiva, who are separate beings and forces entirely and not aspects of each other the way the Catholic trinity is.

There very often isn't a single creator god in polytheism. There might be someone who created humans, but that figure(s) isn't necessarily the creator of all reality. You can look at Norse and Greek mythology for examples.
