If they would mean that it is necessary to have a "god" to:
1, keep people in line.
2, make people give you money.
3, force a big group of people to do "good"
4, keep the power to yourself (catholic church for example)
Then yes, I understand it is a necessity for them to have people believe there is a deity. Whether they believe that themselves or not.
However, if they mean that god is necessary for the world to exist in the first place, that is just a big pile of cow poo poo.
