Considering that is a fact that Morals and Ethics have been a part of Humankind far, far longer than have the usurped biblical/religious versions, then the answer is most certainly Yes, as an Atheists I am a moral human being and have a meaning in life by which I live each day.
Let us take a ' biblical moral' for an example here; Xtianity tells us that Cannibalism in any shape or form is AMORAL, YET it allows its followers to SYMBOLICALLY take part in the 'partaking' of the Flesh and Blood, a.k.a. the Sacrament, of their Founder Jesus.
Is that not just Cannibalism merely disguised in another form, logically and rationally?
