Well ..... first book you will need to read is a dictionary ..... it is spelt as atheists.
Anyway, spiritually does not need a figurehead. I am a buddhist, I am an atheist. Buddhism believe everything and everyone are equal, there are no supreme beings. I have a feeling buddhism are more spiritually inclined then christianity.
Now, since you claim CREATOR ...... tell me please, why do you have two sets of rules? one for the alleged creator and one for the alleged created? From the way you write, you sounds like some Jehovah Witness who push down information that is half truth.
For example, Which german U boat captain said that? If you read astronomy book, had you wondered why your creator created so many useless planets and space? Is it because he is a dim-witted reject from the academy of gods? You claim atheists are not spiritually inclined, but it seems to me you have little knowledge about atheists and it is all through hearsay, objective views and mindless rationalisation, a common trait of Jehovah Witness.
Am I getting it wrong?

For atheist .... you are wrong .... they need to search for the word "athiest" ...... maybe it is in their genes they cannot spell atheist properly.
