It doesn't. The same as defending the flat Earth. Neither matters so long as one believes that God created it. There is no religious importance to the subject of the Earth's shape at all.

But only one of these options is objectively true.  We don't change the shape of the earth by our feelings about it.

Because the earth really is a globe.  We use the evidence of our senses and reason to understand truths about the physical world.  And all truth honours God.  God is Truth and the source of truth.

The shape of the earth is not a mystery of faith that we learn through Revelation.  It is not part of any religion.  It is just the physical reality that all men can see.  Observation and reason are available to all people, regardless of religion.  Pagans and Catholics all believe that water is wet and fire is hot.  I do not become tainted by paganism by sharing these beliefs with them.  

Globe earth is a part of the false religion.
It is never observed in physical reality. Never.

Are you implying that some people believe that the horizon is vertical?

I am stating that the horizon is horizontal.

No, but there are dopes who "swear" they can see the curvature.

.
There never has been and there never will be any depiction of a Theodolite shooting a level line of sight from a promontory of even a few hundred feet toward the horizon which shows the horizon "rising to the level of the viewer" as flat-earthers keep chanting without any evidence.
.
There never has been and there never will be an intelligible explanation for why the full moon faces with its sun-illuminated face toward the earth from high in the sky, from the flat-earth hypothesis which places the sun above a "flat" disc earth at nearly 90 degrees to the line of the moon's light as viewed from anywhere on planet earth.
.
There never has been and there never will be any "flat" earth plausible geometry describing how a quarter moon makes the angle it does to the sun (while insisting it and the moon are some 3 thousand miles above the earth) twice each month for all to see. 
.
There never has been and there never will be any reasonable excuse for the fact that a ship or plane traveling due east (or due west) along the equator does not have to turn right (starboard) or left (port) in order to remain on the equator and due east (or west as the case may be).
.
There never has been and there never will be any "flat" earth demonstration of WHY two parallel courses once embarked will in due time collide with each other on the real earth, since they don't do that on the "flat" earth model.
.
There never has been and there never will be any reasonable "flat" earth explanation for how any weighted object in a vacuum will consistently be pulled in a perpendicular direction from the horizon line regardless of where on the real earth the experiment is conducted.
.
There never has been and there never will be an explanation for the numerous flights of aircraft that pass over or close to Antarctica and traverse a distance too short to be plotted on a "flat" earth model, when many pilots, co-pilots and navigators who routinely fly such courses have and will continue to attest.
.
There never has been and there never will be any honest video showing the horizon unable to conceal distant objects beyond the curvature of the earth, even while the refraction of light through the water vapor above a body of water makes it appear otherwise, since the progressive foreshortening of such objects belies the distortion caused by the refraction.
.
There never has been and there never will be a seagoing navigator using a sextant and sea charts who can accurately plot his course over a great distance overseas, when he presumes the earth is "flat."
.
I can go on.............

Forget what globe earthers hurl at flat earthers...

Forget what globe earthers hurl at flat earthers...

.
But whatever you do, don't forget the simple facts that flat-earthers can't cope with!
.
The circuмference of the earth is about 25,000 miles which means 360 degrees of curvature takes 25K miles to transpire.
.
Divide 25K by 360 and you get 70.    (69.444 rounds off to 70, and 70 x 360 = 25,200 -- close enough)
.
Therefore, each 70 miles a plane "dips down" one degree to follow a Great Circle route.
.
Any plane that flies over the equator, for example, only has to "dip down" one degree in 70 miles to accommodate curvature.
.
But any plane flying has to correct up and down a lot more than one degree every mile or two, so the one degree of correction needed every 70 miles for curvature is insignificant compared to corrections for normal, ambient disturbances.
.
You can compare it to driving your car down a very straight highway -- why don't you just tie off the steering wheel with a rope to keep the car going straight, and then you can take a nap?
.
The fact is, even with a very straight road, there are tiny bumps in the pavement or camber to the right or left, and little gusts of wind from the left and right which make the car drift off course. So you have to make small corrections all the time if you want to stay in your lane. Your corrections amount to one to four degrees of adjustment every quarter mile, so after one mile you might have corrected about 8 degrees left or right depending on conditions, maybe more. Over 70 miles that makes 560 degrees of correction.
.
Then imagine this highway has a very slow curve in it so that every 70 miles you have to have turned a total of one degree to the right to remain exactly in the center of your lane. Why would you ever notice that one degree when you normally make about 560 degrees? Are you going to notice it was 561 this time, or 559?
.

It's true.  I've seen lots of nasty comments directed at both sides.  I'm sorry that globe earthers do that.

.
Is that an example of a "nasty comment" to which you refer?
.
Or, is it a coherent, logical post with examples and context but flat-earthers have no response?
