I'm an atheist but I'm considering religion.

I think there's a good argument for the human brain to have a need for something to fill the role that spirituality fills.
And from history we see that the main method of doing that has been to anthropomorphize rules about the universe, including the mechanisms of our own minds.
By that last point I mean, for example, that a religious person might assign "evil" to some thoughts—believing them to be sourced from the devil or his demons—and "good" to others—like the greeks and romans who assigned causation of some inspiration to "Muses".
This builds a mechanism for thinking with relatable humans as the causes—something of a social network, which is quite natural to humans..

Religions pop up on their own irrespective of location and time in history.
I mean not to argument that they are right; but that they are doing something very naturally human.

I guess why I'm really here is to ask you:
Remaining an atheist, if you were to pick a religion or two to practice, which would it be and how would you remedy the contradictions with your scientific beliefs?

For family reasons I pick my first as mormonism, and out of burning curiosity Hindu as the second.
