4. Why do you think that you are special?
People often do not look at themselves relative to the enormity of the universe. You are one of about 6 billion humans on the planet at present. The planet Earth is merely one of 9 large bodies that orbit the Sun, a medium-sized star in one arm of the spiral galaxy known as the Milky Way. The Milky Way contains some 400 billion such stars together with pulsars, black holes and all kinds of wondrous objects. And then there are all the other galaxies in the Universe, approximately 100 billion of them, with an average of 100 billion stars each. And new stars are forming all the time. The Universe is continually expanding, from it's starting point at the Big Bang. That doesn't even beginning to give an idea of our insignificance if recent multiverse theories (which postulate that our universe is but one of many) are true!
How significant are you? Why do most religions assume that we, on this planet - one species of a million - are chosen? And why do we assume that we are the height of evolution? Admittedly we are by far the most complex organisms upon this planet, particularly in brain structure and function. However evolution hasn't just come to an end - it is a continuous process, although it is somewhat complicated by the fact that mankind doesn't just need to adapt to its environment but adapts its environment to suit its own needs.
God is dead
"God is dead. God remains dead. And we have killed him. How shall we, the murderers of all murderers, console ourselves? That which was holiest and mightiest of all that the world has yet possessed has bled to death under our knives - who will wipe this blood off us? With what water could we purify ourselves? What festivals of atonement, what sacred games shall we need to invent? Is not the greatness of this deed too great for us? Must not we ourselves become gods simply to seem worth of it? There has never been a greater deed - and whoever shall be born after us, for the sake of this deed he shall be part of a higher history than all history hitherto."
