The problem is that our brain is not designed to understand such complicated theories. To make things worse, for thousands of years, mankind has been selected on followers of myths, legends and believers in a god. Those who did not, and tried to find logic answers, were suspicious (because, basically, they challenged someone’s claim to power, derived on the myths and gods) and they were killed. So, throughout evolution, mankind has become dumber and dumber and its brain was even more and more elongated from understanding the universe. Now that we finally got the technological means and the liberties to explore these things, we are stuck with a brain that prefers stories of trolls, sorcerers and demons, or of supercreatures with a white beard and a white gown sitting on a cloud in the heavens and getting pissed off when a man and a woman are eating apples in his garden.
