"I, the atheist, believe:"
...and your 'argument' fails at Step 0: I, the Atheist, only accept hard solid empirical peer reviewed evidence - facts - based on the Scientific Method. That inferior word 'Belief' is the preserve of the inferior fundie. For you cannot spell 'Belief' without the word LIE, which is what your whole set of 'beliefs' are based on.
1. Until the likes of WGC can prove, via hard solid empirical secular peer reviewed evidence based on the Scientific Method, the existence of the so-called 'Soul', then anything the likes of him claim have no right to be accepted. By anyone of sound mind, least of all by me.
2. A rainbow doesn't physically exist, yet it can be seen. So unless your 'God' can do a Morgan Freeman in "Bruce Almighty" to absolutely everyone on the planet simultaneously, then the whole concept of the so-called 'Spiritual' /'Supernatural' is destroyed by that rainbow which doesn't exist, but can be seen, and your 'God' doesn't exist.
3- We Atheists can be good & civilised to our fellow human beings, because we can. Just ask the likes of SpukiKitty about the Wiccan Rede: 'An it harm none, do what thou wilt'.
4- "Assassin's Creed" is a good game, but would be better if there was a version that was set in the future.
