Ive never understood the argument that life is meaningless without god. I would say that life would be meaningless with a god. If you can only find meaning with a an evil monstrous god whistling the universe into existence who can snuff it all out again on a whim and crawling to this megalomaniac for eternity seriously turns you on then your daddy complex is sad in the extreme. What challenge is there? What discovery or adventure in a universe where everything can be answered with the words ‘magic did it’? What a pathetic universe that would be. Utterly meaningless and devoid of life.
