Has it not been proven that the earth isn't at the center of the universe? That the sun doesn't revolve around the earth?
That right there is nitpicking at unimportant details - in particular, some that are not actually said to be fact by the Bible. The whole earth as the center thing was philosophically deduced by church officials just because it made sense to them. The logic goes:
We are the only things we know of that talk, build, etc. We have this religion we believe made us. Why wouldn't the Supreme creator not make the highlight of his creation in the center? We've spoken of this before.
If you want to start claiming proof and what not, get up and do some research. You will find nothing conclusive - people have been trying for ages to do so and come up with nothing so solid that it could be officially recognized by any reputable group.
To top that off, many portions of the bible are heavily debated within and between churches as to whether they are meant as an account of true events or as a story. So trying to use any of them as "proof" against Christianity is an inherently flawed plan. This, too, you have been told before.
My point here is that what you are doing, in insisting on these statements of yours, amounts to antagonization of religious Christians, whether you intend that or not. It's pointless, irritates several, and you should give it a rest already. I will say no more on this matter, and kindly ask that you do so as well.
