What is actually said is that if atheism is defined as "lacking belief in god/s" then it follows that babies are atheists.
That matches what @SkepticThinker has posted.
What may be meant is that there is no "built in" religious "urge" that is inherent to humans. I kind of doubt that too
Rightfully so. Parents are the first god in which every child instinctively believes. Human's are hard wired for god-belief. I looked it up at one point, there's scientific research supporting this.
Asking for "evidence" for low probability claims is really no more that a statement that I don't consider it worth the effort
If God is, by defintion, never going to be proven, then finding no falsifiable evidence confirms that defintion.
