Logically, if 'christ' fed 5000 people on loaves and fishes then 'christianity' cannot be applied to more than 5000 people.
Biblical numbers have nothing to do with - real- numbers.
5000 could just as well be 5000 years.
So there is no comparison between religion and secularism.
The model for religion is taken from Egypt and the Pyramids where the 'world' is flat (as each person lives in their own little 'world') has four corners, as the base of the pyramid has four corners and where people find their own level just as water is said to find its own level.
Water may appear to be 'flat' but is always curved as it follows the curvature of the Earth. We are mostly made of water.
All Einsteinian 'physics' deals in relative matters relating to religion whereas Newtonian physics deal with the real world according to secular thinking. Newton probably prayed as well.
Why should a dog believe in god when you are only made in a (mirror) image?
dog|god
Where | represents a mirror or 'looking glass'.
OK, I would need to reverse the g and the d to do this properly but that would be a complete giveaway.
As the truth is represented by a duck I leave you to draw your own conclusions. A duck also represents Zero or O, o and 0
Where the two curved lines intersect in the representation of a fish, this is called the vanishing point.
