Sure I think most current religions suck. But for some reason, maybe someone will do a PhD on it one day, intelligence needs a 'god' to handle some environmental problems. So if intelligence needs a 'god' your better off trying to propose a different religion rather than fighting the impossible battle of removing religion altogether.
The problem with most religions is that they are either started as, or guided towards, a top-down means of controlling the masses. The latest varieties such as new age earth-worship, technocracy and spiritual humanism are just as bad as many ancient religions despite being marketed as rebellious and liberating for disenfranchised individuals.
That said, I think the drive towards spirituality is very much a part of human nature and it is a sense of awe in the humbling amount of unknowns that still exist today. For many, nothing screams "prime mover" quite like the exploration of the cosmos and the big bang theory.
