Religion does not require belief in a deity, either. There are plenty of Jains that are highly religious but have no concept others might term deity. The same could be true of Advaita Vedanta, some forms of Buddhism (though not all) etc. Star Trek has dealt with searching for the divine for decades. I don't see how this will be any better. If you simply are dealing with a higher power beyond human comprehension, that's pretty easy in Star Trek.
But, going out on the ledge here, I think trying to develop and run society PURELY by deduction and without "Faith" , even if that faith is nothing more that there has to be something better out there, there have to be breakthroughs we can't logically explain yet, there have to be codes of ethics worth following even if we're all just nothing more than 80 year walking storage units of maggot food. The best things we believe in have to be worth something intangible but utterly necessary, and worth continuing our species onward, ad astra per aspera. What does a human need with a starship? That lottery chance of finding God, or failing that, cool stuff to show off on the news.
I've noticed on scientific forums lately a greater and greater kneejerk reaction to be the first to shoot anyone down who has a hypothesis that, while scientifically plausible, does require a challenge to the standard model, or a rethinking of current opinion on genetics, etc. It gets a herd reaction of cheers from the Greek Chorus for these would-be Randy the Magnificents who are saving everyone from dreamers. Truth is they are nothing of the sort, just pseudo-scientific bullies. Because they are not defending science. If they were these challengers would rise and fail on their own merits, upholding standard models. Those models SHOULD be challenged. They are not Laws. This "All the World is Known" mentality has crept up before, and after awhile someone brilliant capable of seeing things in knew ways tears it down. And oddly enough, those people tend to have a faith of some sort that it could be done.
