Except we have the foresight to know everything will end. Even if we were to produce 100 000 000 perfect replicas of our genes they would still hit the same wall— extinction. Further, whether we have free will or not (prolly not), we're able to coopt the gene platforms to further non-procreative aims.
It's a bit like saying the point of a TV show is to earn profit for the people who bankrolled it. Well, yes that's why it's here and literally the only thing that will keep it going, but you can do a lot more within those constraints than play out the material reality.
The meaning of life is very simple: life has no meaning unless you create meaning. What that meaning is is going to differ from person to person.
The meaning I give to my life is to do everything I can to further human knowledge and to learn as much as possible myself.
For other people, it could be exploring the world, finding inner peace, helping as many people as possible, gaining power/money by any means necessary, etc.
All valid, some more well-intentioned than others. IMO if your goal is to do good by yourself and/or to others without actively seeking to hurt others, there isn't really a wrong answer.
Personally I feel like it is a dumb question. Life gives you meaning. By that I mean life enables the creation of symbolic truths. And what enables life is a different question.
Y'all need to look into some of the less boring fields of philosophy, plenty of philosophy says physical pleasure is good and we should be having and enjoying it!
"Don't forget the real business of the War is buying and selling. The murdering and violence are self-policing, and can be entrusted to non-professionals. The mass nature of wartime death is useful in many ways. It serves as a spectacle, as a diversion from the real movements of the War. It provides raw material to be recorded into History, so that children may be taught History as sequences of violence, battle after battle, and be more prepared for the adult world. Best of all, mass death's a stimulus to just ordinary folks, little fellows, to try 'n' grab a piece of that Pie while they're still here to gobble it up. The true war is a celebration of markets. Organic markets, carefully styled "black" by the professionals, spring up everywhere. Scrip, Sterling, Reichsmarks, continue to move, severe as classical ballet, inside their antiseptic marble chambers. But out here, down here among the people, the truer currencies come into being. So, Jews are negotiable. Every bit as negotiable as cigarettes, cunt, or Hersey bars."
