A scientific discussion can only last so long before it becomes a cultural discussion.
It is odd that the discussion would get hijacked at a point where the excitement over the original finding has waned.
No matter how people with various cultural views want to spin the science, the reality remains that we have an overwhelming amount of empirical data support general relativity (GR). Not only that, but even more importantly we have predicted so much and built machines that only work correctly because they use GR in their computations.
In other words, there are many details we have confirmed as true already.
The same for evolution, a field which will continue to be refined. Some issues are settled, such as general time periods and that we have shared ancestors with other primates, mammals, etc on up the line. There are many details that will take time and resources to fill in. Nevertheless, we have seen how this model combined with geology and genetics repeatedly confirms our expectations.
The reality that scientific discovery will never be finished is a wonderful quality of science. We are always looking for more data to better understand the world. We have come so far and know so much compared to a century or two ago, but we still have so far to go and always will. There will always be measurements beyond our grasp or potential observations we don't have access to due to the restrictions of location or time.
The universe may even reach a state where the expansion has reached a point where we can no longer access the earliest moments of the universe with stronger telescopes. If you think about it, this is a profound point -- profound because any intelligent being beginning their explorations of the universe at that time will not have the ability to make many of the landmark discoveries we were able to make with out instruments in our epoch.
