There is plenty of science with a non-reproducible basis. Richard Dawkins has gone as far to say that evolution is fact. And yet we have never observed one species changing into another - sure, the headlines say we have, but when you drill right down into the source material the best you can find is “these creatures do not normally reproduce with each other”. Note the wording: “do not normally”. Not “cannot”, which is what the headline fundamentally requires in order to be truly accurate.
Evolution in complex organisms takes millions of years so no it’s not something you’ll witness in your life time. The evolutions you do witness are in faster aging, less complex organisms such as microbes which we can practically witness evolving in real time. Evolution isn’t a theory, it is an inevitability, those that survive their surroundings pass on their genes, that is all that evolution is.

Also we can see evolution at work when bacteria develop resistance to medications.
Right, that’s the type of microbial evolution I mean
