First I dont want to criticize anyones faith or hurt them.....but ive been thru this as well. I grew up with a family that all believed. You were expected to believe as well.
Belief isnt a choice though. You either do or you don't. Belief is a strong action in the human mind....its not something you can make up or just take away on purpose.
There have been lots of discussions on religion, faith,...what they mean, whats required, why is it required, etc etc
Its a philosophical rabbit hole that can go on & on. Some people make careers out of it.
If you are contemplating belief...I would suggest looking at the serious criticisms of religion & faiths.
For instance, for criticism of Christian ideas (the one I am familiar & grew up with)...there is a lot out there and the internet now makes all that easy to see.
Bart Ehrman is a good one to listen to....hes a professor that was once a believer (till not too long ago)

There are various others out there as well that show you the other side of the conversation.
The same goes for all the other religions out there as well. There is a lot of information out there now.
Knowledge is power & freedom...but it can be hurtful as well in this case.
I know all to well. Getting to the point I am now was a process that was heartbreaking..
