No, because I believe in spirituality.
Now, if you believe in supernatural reality, I apologize. I am going to assume that you do not believe in supernatural reality.
I believe that it worked the other way around as well. If a symbol is inspired by the super/preternatural, then it's in that particular lexicon. The fertility symbol (I think it besides the point to get into the specific of the fish at the moment, and if/ifnot it was a fertility symbol, I'll give you that for now because it's not a big deal) was tied to a belief that rituals could invoke super/preternatural intervention, or, such spirits could be controlled and made to do a particular thing. When Christianity assumed more ancient practices/rites, they were maintaining the belief that a supernatural reality existed.
CS Lewis, among others, had the idea that the ideas could have been hijacked the other way around. Take the crucifixion. If you believe in demonic spirits (maybe you do, maybe you don't, just work within the belief for a moment), it is possible to believe that they would take the glorious moment of Christianity (crucifixion/resurrection), and debase it earlier in history by associating it with something inferior. Or, they could be what Lewis called "happy dreams", where people in the past had a vague idea about what was coming up, and articulated it as best they could.
Regarding December 25th, it was more of a convenient date to pick. Before Christians celebrated Christmas, they celebrated the feast of the Anunciation (the conception of Jesus, when Gabriel appeared to Mary). Being the kind of people who liked patterns, they assumed this would have happened on the same day as the crucifixion (meaning Jesus' life would have spanned an exact number of years). The date for the crucifixion was held to be late March/early April, and that date varied in the opinions of early Church leaders. Anyhow, 9 months after late March, early April, gives you late December, early January. Before Christmas was celebrated, the feast of the Ephiphany was celebrated. That became associated with the New Year. And of course Christmas came several days before the Epiphany. In December 25th they found a convenient day for Christmas (because it was already a festival). But like the Romans, they believed in the supernatural.
What I'm saying here is that people when people who don't believe in the supernatural hijack the symbols of people who do believe in the supernatural, it smacks me as ulterior to their essential beliefs. But I suppose the point might not to be faithful to their beliefs. I've always believed that the Darwin fish is meant more to mock the beliefs of others, or to give certain people the symbolic mechanism to feel intellectual satisfaction. We all need our own coping mechanisms I guess.
