Hollywood assumes that space aliens would try to kill us to take over our planet's resources for themselves.  But what if we don't compete for the same resources?  What if we can peacefully coexist because we occupy different ecological niches?  Why would they need to steal our farmland if they can artificially synthesize food?  Why would they steal our oil and gas if they use nuclear fusion for energy?  Unless they needed to steal resources from us, there is no particular reason to perpetrate a holocaust against us.  Seeing that they don't need our resources, they leave us alone.  They merely abduct a few of us to satisfy their occasional sexual curiosities and breeding innovations, and this they do merely for their own purposes – not to advance human evolution, but rather to advance their own genetic properties by means of genetic engineering, to which end our DNA occasionally proves useful.  Why should they care about our evolution?  It makes much more sense that they are perpetrating sexual encounters with us to further the cause of their own evolution.

     Why invade earth when everything you need is in your space ship?  If the aliens have been living in deep space for billions of years, not being on a planet, then they are adapted to that lifestyle, and have no need of living on a planet.  Staying in the space ship has certain advantages:  A space ship can dodge asteroids and meteors, but a planet cannot; a space ship does not suffer from unpredictable natural disasters like a planet does; a space ship may have better temperature controls than a planet; planets may be home to potentially harmful microbes that could devastate alien populations.  Also, life on neighboring planetary bodies provides a gene pool from which the aliens can draw, for the purpose of genetically engineering certain useful life forms that they don't already have in their menagerie of alien slave species.  If they invaded earth, they might cause contamination of this asset.  For these reasons, our alien neighbors may actually prefer to remain in space rather than invade us.

     Therefore, the aliens don't kill us because they don't compete with us for the same resources.  When the Europeans colonized the Americas, they did not exterminate the earthworms of America.  Instead, they subdued members of their own species, the American Indians, and they did this because they competed with the Indians for the same resources.  Likewise, we should not necessarily expect space aliens to destroy us.  Rather, we should expect them to destroy other space aliens, because they compete with other space aliens more than they compete with us.  There is war among the gods, and we are but earthworms on the battlefield, who remain oblivious inside our burrows, relatively safe from the hellish warfare in the heavens.

The creationist narrative in Genesis 1 is contradicted by many ancient Christian texts.  Instead of an Almighty Creator God, ancient Christian texts espouse that the universe is born from blind arrogance and stupidity.  The angels caused evolution to occur from species to species.  There are many gods, (or aliens?), and the Christian God is just one among them.  Satan the Devil writes scripture, and thus the Bible was polluted with Genesis 1.  Archaeology and modern scholarship demonstrate that Genesis is indeed corrupted.  Cavemen walk with Adam and Eve.  Esoteric prophecies reveal the coming of Christ, and also reveal the dark forces that govern the cosmos.  Such are the ancient Christian writings.

Science vindicates the truth of these ideas.  Evolution often happens too fast for Darwin’s theory.  Gaps in the fossil record indicate that some kind of unnatural force acts together with natural selection.  Astrobiology reveals that intelligent life probably evolved long before us.  The fossil record reveals strange clues that aliens abducted species and transported them across oceans, and that DNA from diverse lineages was combined to spawn hybrid species.  Evidently, aliens influence evolution, and they are the gods of the world’s religions. 

This is not fiction.  All these facts are thoroughly documented in the links above.
