Would you like if all people became atheists?

I think that even if all religions are eliminated there will be many kinds of metaphysics. Religions are just some manifestations of metaphysics but not all the metaphysics. You will find many people (want to) believe in metaphysical aspects. Other people will be very interested to the extent that makes them theorize these philosophies. Others will exploit people metaphysical desires to control them or fleece them. Gradually and over time you will find yourself in front of a new religion.
Circumstances will determine whether this religion is harmful or not, peaceful or not, progressive or not ... etc.

Maybe if we raise our children on scientific thinking and scientific method we will guarantee, to some extent, that no one can deceive them since they will automatically test every piece of information applied to them.

** My answer to the question is the fifth option (otherwise). What is this "otherwise" definitely? I don't know, but it is otherwise anyway.
