I start my world view with the bible and the bible supports this finding,
that people believing in God is genetic.
I have read the bible cover to cover 7 times since leaving the Watchtower and the predominant theme
I found in the bible is predestination.
Predestination isn't genetic, in fact, predestination removes any iota of free-will and would remove any possible genetic component.]
so according to the scriptures some can not help believing and some can not help unbelieving.
And now science and genetics is supporting this biblical view.
Those verses say God decides, also removing a genetic component.
