If you were born in a different region of the world, you too may have a different worldview . That alone doesn't mean your worldview is a false reflection of reality.
No, but it certainly casts doubt on it. The nice thing about a falsifiable claim is I can read and travel and learn from others to find actual aspects of my worldview which can be falsified and by doing so improve it over time.
A faith based worldview does not allow for this because it is a non-falsifiable claim. That, to me, creates challenges for justified belief (epistemology) because from that framework anyone can believe anything and no one else has a mechanism to show them where they might be incorrect (we see this with many religious disagreements in the world today).
How is that view of the meaning of life consistent with your monogamous lifestyle?
It's something I'm working out as I better understand the reality of my species along with the reality of my marriage and my love for my wife. An evolutionary strategy of "impregnate as many females as possible" does play out in some species, but notably not so much in ours. Even then, people like Genghis Khan may disagree. :)
I view these discussions about purpose as being tied to discussions on morality. I do think gene transfer is the ultimate goal (and I see no strong counter argument to that claim), but I also think there are complicated sub goals on multiple levels which achieve that higher goal for the species. For example, affluent societies seem to reproduce less. Could that be a built in mechanism to prevent us from overconsumption which might introduce systemic risk? There are many more examples like this I'm interested in learning more about along the lines of evolutionary stable strategies, but I also temper everything based on my love for my wife as I recognize we are not in the same place when it comes to worldviews. Because I love her, I wouldn't consciously do things to hurt her.
