Basing myself on natural selection, as humans we have done as all other species on this planet have done. We have adapted to our respective environments. There are many species of animals that have adapted remarkably to their environments and to the keen eye you may even see a sliver of intelligence behind their evolution. Basically, they took what they had and made the most of it. Some primates for example are known to use crude tools to obtain food etc. etc. The fact that our minds developed more than our natural instincts I think was necessary for our own survival. It does not make us special in any way we just did what every other species has done to a certain degree.
There is nothing people will not maintain when they are slaves to superstition
