It’s not narcissism. It’s actually a humble stance. I’m not important to a majority of the people on earth. My life is insignificant in the grand scheme of things. I will die and be forgotten. I don’t need to understand these things because they don’t affect my life. I work, stack sats, and try to enjoy my short time on this earth. Knowing about the origin of life is irrelevant to me. I can only speak for myself though. Some people find pleasure in contemplating these things and that’s valuable for them. It’s just not for me. Speculation beyond evolution (e.g. big bang theory) is uninteresting to me.
