No need for it.
If you want to assert Earth is flat and have any hope of convincing any rational person, you need to provide evidence for it.
You need to provide explanations for common, everyday observations which a RE can explain.
You cannot provide round Earth either
Yes I can.
The horizon alone is evidence of a round Earth.
If Earth was flat there would be 2 options, either you would have the atmosphere obscure distant objects with the ground/water fading to a blur with no clear edge, or you would see right to the edge of the FE and only ever see that as the horizon.
But neither of these happen, instead you often have a clear horizon, with the distance to it varying depending upon your height above the ground,exactly as you expect for a round Earth.
Other evidence requires you to accept a few commonly known facts about the world (which you can verify for yourself with long distance travel).
The first involves the sun. For a FE, the sun would either never set, always remaining above Earth, or it would set for all of Earth at once (ignoring slight issues due to mountains).
Instead, we have it always above some point on Earth with it "rising" and "setting" and different times for different locations.
Tying back into the first one, you can watch it set, get higher and watch it set again.
Once again, this makes sense on a RE.
On a similar note you have the direction to the sun.
There are numerous issues with this alone.
By measuring the angle of elevation and azimuth of the sun from multiple locations on Earth you should be able to make a rudimentary map, and in fact you can. For a RE it works fine. For a FE, you get numerous contradictory maps.
A simple example is the equinox, where at 6 am solar time (sunrise) the sun is due east, even though the common FE model indicates it should be NE at the equator, getting closer to due east as you go north and closer to north as you go south.
Assuming an error of roughly 1 degree, then just going to 60 degrees south (and also considering those on the other side at sunset) you have the sun needing to be 382 000 km away from the north pole, while being directly overhead a location only 10 000 km away.
Simply tracing the path of the sun over the equator on the equinox shows that the equator is a circle in the same plane as the sun's apparent path, and thus Earth must be round, at least a cylinder.
Once again, all this is consistent with a RE, not a FE.
There is also the angle of elevation, which also works well with things like Polaris.
Simple trig should allow you to measure the height of the sun, which is where the FEers come up with the sun and Polaris being 5000 km (or 3000 miles) high. This is the distance between 45 degrees north and the equator, and between 45 degrees north and Polaris.
As such you have a right angle triangle with an angle of 45 degrees, giving the height using simple trig. But using different locations, you get completely different heights.
In general, for each degree you move away from Polaris (or the sun, noting you need to move directly away, if the sun is overhead a location east or west of you and you move 1 degree due north you are not moving 1 degree away from the sun) Polaris or the sun appears to drop 1 degree.
Again, this is completely inconsistent with a FE, yet is exactly what you would expect for a round Earth with a very distant Polaris/sun.
Then you have the celestial poles, where the north celestial pole is always due north and the south celestial pole is always due south, always 180 degrees apart.
In order to have this on a FE you need to have 2 lines which are non-colinear, intersect twice after some finite distance which is completely impossible.
But again, this is exactly what you would expect on a round Earth, with the north and south pole merely being Earth's axis of rotation.
Then there are things like the fact that water remains level, yet if you observe an object well above the water quite some distance away (best if it is moving away from you or you are moving away from it), the bottom gets obscured first, indicating the water is not following a straight line between you and the object and is instead curving up from that straight line (with the straight line being below level).
You then have the phases of the moon, which is best explained as the sun lighting up a portion of the moon and us seeing that portion, with a lunar eclipse being Earth getting in the way and thus the dark region being Earth's shadow.
You have the sun and moon remaining pretty much the same size and travelling at the same speed over the course of a day, indicating they need to remain a similar distance from you and thus "circle" a point near you (or a point on an axis passing through you, circling in a plane perpendicular to that axis), with it applying to everyone on Earth indicating they must be far away, and thus everyone on Earth should be seeing them the same if Earth was flat, including the same direction.
So no, there is mountains of evidence for a RE. There is not a single shred for a FE.
i would answer from flat earth theory question
Except FE garbage doesn't have any actual answer, just pathetic attempts to skirt the issue.
and bum we waisted each other couple of hours.
You would be the one wasting people's time, not me.
I would be providing rational arguments and evidence, while you provide crap and baseless claims.
If you had knowledge of photoshop and alike as i do . You would clearly see that NASA pictures are fake.!
No you wouldn't. The best you could do is show that they could be fake, not that they are fake.
If you wish to claim they are fake (or that one would clearly see that they are fake) you would need to provide evidence that they are actually fake, not just that they could be faked.
