go on a few atheist forums and you will see a lot of denying God exists and attempts to persuade believers to give up their belief.
this guy verbally denied God by claiming no belief based on a supposedly lack of action by God.
He said I’ve never believed in God. How can there be a God when my son died?’
an opinion is a judgment formed about something,
when you look at the sides and choose one you are performing an action.
it absolutely can be. many atheist are atheist because they just don’t want to follow God’s moral law.
but their morals are subjective and evolution doesn’t require any morals at all. it is just a communal get along
