Centre of the world

There is a super-supermassive blackhole, in the centre of our Galaxy that is probably bigger than any other galaxy's black hole. A hundred times more massive than the average central black holes in the galaxy. This is strange, why should we inhabit this exact one AND be the only known intelligent sentient lifeform.
We are in the metaphorical sense at the very "centre of the world" in this aspect, this is odd concerning the Copernican Principle that has held true in so many branches of science. Here are a few examples. We are not inhabiting a planet that has a star circling it. Copernicus enlightened us on this. We (as humans) are not a special creation in the nature, we are just one among many forms that have evolved. Darwin enlightened us on this.  We do not inhabit the only continent. Columbus enlightened us on this. We do not have to read the Bible in an obscure and mostly unused language. Martin Luther enlightened us on this. We are not a species that last forever. It is easy to go as far as remembering that Buddha told that our ego is just one among the many things. We are not a genetic culmination point of nature. A transhumanist might argue that evolution is just beginning about to begin again in a new groove and indeed humans have just been a stepping stone. We are not privileged persons in command of their will by a matching reason. Freud enlightened us on that. As there are libidinal and aggressive drives running us in our subconscious mind. We are not at the apex of the form of historico-social structure (in opposition to Francis Fukuyama theory of the end of history and Marx's scant visions of communism) - there are likely to be many others. We humans do not have the only self-conscious minds on the planet. We do not have monopoly on god there are many gods. Human rights are universal not singular, from then on royalties are obsolete as forms of government. Rousseau enlightened us on this. Human rights are not based on the conditions of any specific nations but happened as the spirit of the times. Jellinek argued that. The list is long.
