How so? Evolution, as far as the basics go, such as Natural Selection, are fairly incontrovertible. Abiogenesis, which is actually a separate issue, is still being investigated. Do we have all the details worked out on all facets of evolution, on every genome & every twig of our family tree? No, & some things may never be completely discovered or understood, but "Evolution" is a fact, & the odds of it being overturned, even if 'panspermia' ends up being the originating force, are slim to none.
So, what about "Evolution", a very broad subject, do you wish to talk about? In a forum such as this I'm afraid you'll need to be a bit more specific.
