Hi all, I'm new here so please forgive me if this has been explained somewhere already. Lately I've been reading about cosmic evolution and I find it hard to understand how it cannot be a generally accepted theory within the scientific community. At least according to wikipedia it seems that it is somewhat speculative still. I know that biological evolution is generally understood to not describe the origin of life (abiogenesis). And, going further back, I understand that we haven't fully understood the complete process from the early universe to formation of amino acids. But still, isn't it clear that certain states in the cosmos has evolved into other states? And that evolution by natural selection in the biological life on Earth is just the mechanism by which the universe has evolved during a certain time at a certain place (irrespective of how it has evolved in other places at other times)? In other words, if someone does not believe in cosmic evolution - i.e. that our cosmos has continuously evolved from the Big Bang until today - what do they believe? Please note I'm not asking about multiverses or about whether black holes can give birth to other universes and such. To me that still is a form of speculation. I would just like to understand if the scientific consensus that we have biological evolution on this planet can be extended to a consensus that we have evolution in our universe. And if not, why not? Thanks!!
