It means "No God", or "Without God". It's original meaning was "denial of the Gods". It does not refer to a lack of belief in God, but to a belief in the nonexistence of God or Gods. "Denial" of their existence. An atheist is not agnostic, he has taken a stance against the concept of God and against those who believe in God.
Babies take no stance, they have no belief. Agnostics take no stance, they have no belief. Atheists take a stance - against theism. Therefore babies are not "atheists". You are a zealot Terry. Babies don't share your zeal in attacking Theism. Stop trying to co-opt newborns into your religion! LOL.
Jeepers what a mess!
There are dozens of contrived deifnitions of Atheist and I made mine crystal clear. Your dragging in OTHER definitions has absolutely nothing to do with me or mine. (You know that.)
You use the phrase "lack of belief." That is a pejoratively contrived description.
An honest person doesn't LACK lying. An honest person speaks WITHOUT lying.
A baby does not LACK God. A baby is without belief. Remember?
A baby is A-Theist (A=without Theos=God) without God.
I do not take a stance against God. I take a stance against non-thinking irrational dishonesty pretending to represent a description of God.
Since you have no argument and no ability to present a reasoned defense without blathering the same repetitive strawman I think you have self-identified as the Zealot.
Co-opting infants into a religion which is without God makes about as much sense as your entering a discussion about Atheism without having the bona fides to acknowledge you are out of your depth.
Stop embarassing yourself.
LOL indeed (Losing, Only Losing).
