Do you think science will ever be able to answer philosophical questions about life?

I believe that we are here because of a chain of events. Our purpose is what we feel it to be as individuals, but there is no wider purpose. It's like asking the purpose of a pothole. It's there because of what came before. It's part of a chain of events. Sentience brings existential questions but there are no global answers. It can be whatever you want, the process will remain the same. You will exist and then you won't.

I have never felt the need to have a bigger purpose. I feel that where science comes in is to fill the gaps in our knowledge so that we don't have to make deities out of rocks.

In a way. Because we're animals, there's a lot that can be explained.

My real question is why do we complicate our existence and expect grandiose meaning?

I'm not sure there is a purpose and the older I get the more I think it's folly to look for one.

We're just living beings.
No more than the animals or the plants or the microbes.

The living cells that went into creating me or you might just as easily have been cells used to create bacteria or disease.

We are accidents of chance

I think the consensus is that there is no purpose or reason. Just a random chain of coincidences.

But other related questions like "what is the best way to live life" are more complicated. I think that's too subjective to answer scientifically, though ever is a long time, so who knows?

Physics and philosophy probably don't mix. It explains how but not necessarily why.

I think our purpose is to pro create.

Science developed the fine tuned universe theory, which answers some pretty big ones
