The answer to the title question of this thread is because religious people generally have more children than nonreligious people, and since religious people typically indoctrinate their children in their religion, their religion tends to grow.
At the link from the opening post, one can see the birth rate being the significant factor. This is why Islam is growing the fastest of the religions they cover, and, if current rates continue, will eventually become the biggest religion in the world.

As a Christian, you are not going to tell us that that means that Islam is true, are you?
Basically, reason has nothing to do with what religions are most common. It has to do with having children more than anything else.
This is why there are nearly zero Shakers these days, but plenty of Catholics. Shakers do not believe that one should have sex and have children, so they do not automatically get new members. But the Catholic Church forbids birth control (though many individuals ignore that), which helps increase the number of Catholics. This has absolutely nothing to do with who has more accurate beliefs or more reasonable beliefs.
If you were going to make the claim that growth of a particular view of religion made it correct (which would be totally moronic), you would be committed to the idea that Islam is true, as it is the fastest growing religion in the world. It is not because it is reasonable, it is because Muslims are having more children than other groups.
