Yes - the Bible is the final word in any matter.
It matters where truth is concerned.
The Bible does not say "The Earth is flat." - but, if it did, would people believe it?
The Bible indicates to us by what it does say that the Earth is not a spinning ball flying through space and orbiting the sun.
The Bible describes the stars as being different than the sun. (i.e. - the sun is not a star.)
The Bible does not support the idea of "planets"; rather, what we call a 'planet' is actually a special form of 'star' ("wondering star"). The Earth is not a 'planet'.
The Bible very clearly illustrates the sun, moon, and stars as all being present together in a spatial region of finite size - with bounds 'above' and 'below'.
The Bible descibes the Earth as being stationary and non-moving.
And, there is more...
Much of this is fallacious at best. First, you have not provided any Scripture references despite your claims that the Bible says such and such.
The Bible
does not say that the sun is not a star. It says that God made the stars also. The sun is special to us because of its proximity, as is the moon (the two 'great lights'). God did not specify the nature of the other lights visible in the sky, but later in Job and other places, He does mention them. You've made your argument on what is
not stated clearly.
The universe
is a spatial region of finite size (though extremely vast). The nature of the boundary above it is not laid out in detail, and as such, we do best to avoid dogmatic statements about it.
The Bible does not state anywhere that Earth is
not a planet; again, you are making an argument from silence.
Context and some understanding of the original languages is critical when delving into this kind of argument. Trying to make your case from the English text is simply foolhardy.
