By taking any belief that requires use of your imagination you are entering into the area of your mind that holds religion. When you don't understand the reasons for using 3 sinks of water to wash dishes but you follow the practices and procedures put in place by others you are acting out religious beliefs.
We consider religions to all have a story and a set of rules and be about where we came from and where we are going but our brain uses "belief" when we simply don't understand and we are relying on teaching from others.
Our entire society is built on belief systems that we hold and enforce on others, a lot of these beliefs and practices are in need of upgrading because we are smarter as a society today then we were thousands of years ago when we feared the falling of the sky.
Belief in the old way of doing things, regardless of the topic, is religion. Our prison system is held back and similar to one from thousands of years ago because we believe it was working. Our government is something we believe in and certainly it brings out the zealots who believe in their parties with a religious zeal.
Reality is larger then a single human brain can understand so we bridge over understanding with belief, even in our own jobs and lives we have faith in our guides and YouTube videos and we use belief and faith to push back our fear of learning new things.
The only issue I have with religion is when we can see the world isn't flat so the religious people change their interpretation and adjust the narrative but they don't discard the obvious incorrect information.
Like science, any real belief system need to be able to be adjusted to match reality. Religions with magical thinking that requires you to deny reality should become a thing of history.
