No living entity created the planet we call Earth. Earth was created, as trillions of other planets have been created, by the rules of the Universe.
That said, the story in Genesis is a myth, created by ancient people, to explain their existence on this planet.
People, aka humans, were created by the same natural processes, over billions of years, that created everything in the Universe. We aren't special, but merely talking monkeys that have evolved more than any other species of life that we know to exist. We believe stupid things, and make stupid decisions because of our indoctrination to rely on stupid beliefs instead of plainly visible truths.
