No, it isn't. Human religions are still being practiced in the 24th century, with direct references to Christianity and Hinduism still being practiced on TNG (and DS9, in regards to Christianity). Native Americans still practice their spiritual beliefs, according to TNG and Voyager.
Kirk said, "Mankind has no need for gods. We find the one quite adequate." ...leading to occasional fan speculation over the years on what, exactly, this arcane philosophy of "The One" is actually all about. Kor
I believe he had seen The Matrix. But between that and the end of ST V, you get a picture of Kirk as something like a vaguely Christian Agnostic. More so when you look at Bread and Circuses, or the Enterpise chapel in Balance of Terror.
That would involve a lot of different dissections and philosophy degrees to understand exactly what a 23rd century man thought of this "one god." However, as is my nature, I did some quick research of people's comments for my own curiosity. Source Source Source In all of this, I can only conclude that someone, somewhere, should be offended
I can't remember where I read it, but I vaguely remember somebody hypothesizing that Kirk's reference to "The One" actually had nothing to do with a monotheistic god, but instead a 23rd-century humanist philosophy. Of course, this was just to rationalize things to be more in line with Roddenberry's thinking instead of the clearly obvious meaning of Kirk's line, which was likely just a bone thrown to the audience because a purely atheistic message wouldn't have flown at the time.

That quote is interesting, it rather sums up the difference between the characters of "there are always possibilities" Spock and "the Vulcan science academy has concluded time travel is impossible" T'Pol.
I spotted this one, but it looks to be a Klingon more than Starfleet. It's blurry, but the cut of the skirt matches the chrome and gold outfits in the foreground, and the upper body is significantly darker. Plus the make up, the boots and it being a room full of Klingons.
Yeah, that's not a male redshirt or a female "redskirt" but another Klingon uniform. The cut of the skirt is a clear giveaway.
