Can Atheist be objectively moral in the case of a possible follower of an infallible?

[AFTT47]

We grow up, we take morals of our parents mostly, then society, and some we decide on our own. How does this compare to morality and goodness through vision through a Guide of God that calls toward God and manifests spiritual states and actions, and guides on how to act?

Our way would compare badly IF:

1. The Guide of God was easily understandable and unambiguous,

and,

2. The God was actually moral.

No need to even worry about the second condition because the first one clearly fails. We have all these moral seekers such as yourself, consulting your "Guide of God" in good faith - and coming back with different answers.

If I presented a complex moral problem to 100 people like you and asked that each of you consult your source of absolute moral guidance and advise me accordingly, I would bet everything I own that I would receive contradictory advice. That's why there are countless religions and numerous sects within each religion. You theists cannot agree. Until you all do, there is no point trying to peddle your absolute morality to us because even if it exists, you clearly don't know what it is.
