Given the huge amount of people and the variety of our brains, egos, ID's, super-egos and levels of personal and spiritual development, it is no wonder that there is a religion for every group, every tribe and every person.
There are also cults, philosophies, etc. So there isn't just one religion for everyone because everyone is different.
To some people atheism is what makes them comfortable.To others, it's Christianity, yet to others it's yoga, or whatever.
In reality, no one will really knows the truth until after death. After death, reality sets in. If there is NOTHING, it's all over. We're just biological beings. If there IS, then, we will have some thinking to do with our spiritual bodies. Some religions believe that this is the time to prepare to meet God and not after we've died.
The saying: "To each their own!" applies.
