Is racial mixing the cause of all our disgraces?

We tend to believe humanity was at first very primitive and undeveloped and then it gradually evolved, but what if it was the other way around? What if we were "godlike" at first and because our very ancient ancestors mixed with some kind of primitive hominid we turned less "godly" with the passing of time until reaching this pitiful state of the majority of humans nowadays? What if we were all handsome, tall and strong at one point and then we became smaller and more flawed due to the lesser blood of the hominids? What if we were wiser and more spiritual and we became baser and materialistic when mixing with the hominid beasts? Could it be that through some kind of genetic memory we suffer because we long to be what we once were but aren't no more? Could it be that even when we are all plagued by this lower kind of DNA from the hominids, to a greater or lesser extent, that we are still trying to further the mixing even more to the point of bringing all of humanity back to this lower hominid lifeform?

What do you think?
