None of these things are funny or true for that matter.
> Evolution itself is pretty much outdated theory.
Evolution as an abstract model is pretty old, but it's not likely to ever be outdated. To this day, it describes accurately what is going on with any kind of adaptive system, not only in biology but also computer science and information theory, and one could make some convincing arguments for physics as well.
> Genetics, biochemistry and ethology are light years beyond Darwin.
It's true that Darwin didn't necessarily know much about the inner workings of what he was observing. All he could do is make the actual observations, and reason about them. This led to a key idea about how organisms develop, and it is this idea that became part of the basic tool set of any scientist, it's right up there with Pythagoras and Newton. Genetic and biochemical research didn't really exist in Darwin's time, but the principles he described are found everywhere you look in these fields. And if it hadn't been for Darwin, someone else would have found this out, it became gradually more inescapable the more data we gathered. In fact, today it wouldn't be called much of an achievement at all, since the mechanism is so obvious and ubiquitous whenever you look at bio data.
> - God could use evolution as a tool. And God could also create Earth with all those fossils underground just for a joke.
Those two are actually somewhat mutually exclusive. Either you believe that some kind of deity "uses" evolution as a tool, at which point people should ask themselves what the point of having gods is if they're not actually doing anything measurable at all.
The second point, although you meant it as a joke, is actually harder to argue with - because it leaves reason so far behind it becomes difficult to have any meaningful discussion about it at all: there is nothing in principle to say against the argument that our whole environment and history could be manufactured. We would have no way of knowing that, in fact there would be no way of knowing the actual age of the universe. It could be 2 seconds old in that case. All we have to reason against this approach is an argument from plausibility and Occam's razor.
