Re: "People will always argue over truth"
No, that's another example of the same confusion. The "facts" we can agree on are that the Earth is here, has been here for some time, and it seems to change somewhat over time, thus leading us to infer that it was very likely markedly different in the past. Oh, and that there exist stories that describe "creation" of the Earth.
But "God created the Earth in six days" is not something that can be observed at first hand, it requires interpretation of the observable facts. This particular one relying on a specific written account being true (and many others being false).
