It's our measurements that are precise. The way nature works is the way it works.
It may be that the conditions for life that can develop as it has on earth are extremely rare in the universe. But there are billions of galaxies, each containing billions of stars some, if not all, will have their own solar systems. The chances of the "right" conditions only need to be extremely small for those conditions to exist in a comparatively small number of places. The reason we are here talking about it is because we must be in one of those extremely rare places (the so-called anthropic pinciple).
As regards the laws of nature, can we be sure that they pertain everywhere in the universe at all times? What about the hypothesis of the multiverse, in which there could be billions of universes, only a small percentage of which needed to develop the kind of physical laws that could lead to life; and we're here because this universe is one of those extremely rare ones.
The idea of "the Creator" merely moves the point at which we have to say "we don't know", as well as being implausible.
The first creation myth in Genesis (there are two of them) is probably based on the Babylonian Creation Epic, Enuma Elish, written mainly in the 12th century BCE. It tells of the creation of the universe and the events that lead up to the building of Babylon, home for the gods. It evolved from Sumerian myths.
Here is an extract from near the beginning:
"the gods were nameless, natureless, featureless. Then from Apsu and Tiamat in the waters gods were created"
Tiamat is the sea, personified as a goddess, and a monstrous embodiment of primordial chaos. She gives birth to the first generation of gods; she later makes war upon them and is split in two by the storm-god Marduk, who uses her body to form the heavens and the earth.
Marduk seems to have been replaced by Elohim, via the Canaanites, a plural form of El (perhaps the Canaanite deity). And Tiamat by "the earth was without form, and void, and darkness was upon the face of the deep (the sea)".
The battle isn't used in Genesis 1, but the parallels are there.
The heavenly bodies seem to have been created to serve the earth according to the story, so would have been created afterwards.
The reason for the Genesis story was probably to explain things for which people at the time had no other concepts, as well as the reason for the Sabbath. Now we understand so many more concepts of how nature works, such as space-time, expanding finite but unbounded universe, Big Bang, evolution, quantum mechanics, and so much more. But the Genesis attempt at explaining how the world came into being was a step on the road to reaching today's knowledge. And today's knowledge will be a step on the way to future understanding for which we may not have concepts today.
