Yes. I agree. It is not about progress or sophistication, it is about success. And a little insect can be there a couple of millions of years while complex organisms are extincted.

The only "meaning" of life is to be successful in terms of surviving and spreading the own genes to produce new beings to spread their genes to produce... That is why they call it "reproduction".

My personal meaning of life is similar: I love my kids and want to grow them as best as I can while being a good example to them.
My father once said something similar to me as I was a kid when I asked him about the meaning of life.
