So first you say that life having a meaning is some invented idea. So you admit the words are pointing at some idea. Meaning has a very common definition in this context: value or importance. I dont see why a fact from history: life evolved from non-living precursors, implies "there is no subjective value to any life because it evolved" which seems to simply be the inverse of the argument, "humans are special because they are made in God's image" (humans not special because not made in Gods image) We know what "meaning" points at. The idea that there is more than one way to live and some ways are better than others. Better is obviously a collective value judgement. Just like any judgement of beauty. A meaningful life is one that you would happy to have lived, a thing you wouldn't trade away, something you would be proud of. It's not reasonable to make an appeal to materialism and say, "these feelings are hollow vibrations of atoms" thats a category error.
