I have not enough english to undestand you completely but i want to answer what i understand.
First you need to leanr that there is not a flat map that everybody accepted.
We know that the round earth is a liae because it is impossible if the atmospher is spinnig with a speed from 1000 milph to 3.000 milph with don't difuses the sky. So the round earth model is completely impossible. But this impossibility don't caused by shape, it's caused by just movement.
There is a lot of models about flat earth, the globe is one of them. Your travel is possible with a hemi-sphere model like this:
This is orlando ferguson model near what i want to say.
Another model is "reverse curve model (inside curve)". This model permits what you say, and compatible with all of the measurements of the world. To understand second model, think the curve earth model is the outside of the curve, and reverse it out to in and in to out.
what I want to say is it is possible a lot of model except round earth or flat earth model that permits sitting on a mountain and see everywhere. don't rely on a single model. Just trust to God never lies.
Intikam, you might understand the speed of the earth's rotation if you looked at it from an "RPM" (Revolutions Per Minnute) viewpoint.
The earth makes 1 revolution in 24 hours. How many RPM's is that ? The same as the speed of the hour hand on a 24 hour clock !
Most Serious Biblical Scholars I know say that you have to consider It in the context of when It was written, what was known at that time, and much of It is metaphoric, such as "the four corners", etc.
Jusf a thought. Maybe if posters such as Intikam could write their posts in their native language and use one of the many "language translator" websites to translate it to English , it would be more understanable and make more sense. On the other hand , maybe if we translated English to Turkish, that would help.
