The Right-Wrong Hologram

This links to the religion issue:

Gilbert Gerber's view on religion. 

Is religion necessary? The question is whether we as necessary? 

Suppose there is a God, would the decision lay with us on whether
religion is necessary? How can religion be necessary without a God? A
social structure or system is necessary and if there is a God,
religion would be of the essence to our existence.

And I believe religion is necessary.
