Is the Earth Flat?

I know there are a lot of flat earthers on platforms like Steemit and Hive so I guess there must be a few here on Blurt. Now what is the idea of a flat earth? Just that an Earth which is flat is under a dome and the Sun and Moon translate around the upper levels of this dome (hopefully they don't crash).

For my part I believe the earth is roundish in shape and we move around the sun, but actually if you think about it, it is kind of hard to prove it is round, I can get a counterargument for every pro round earth idea I make. And the fact that NASA doesn't have a photograph of a round earth taken, let's say from the moon, doesn't help me out a lot.

One problem I see for the flat earth theory is if the sun orbits above us under a dome why are the north and south poles such cold places and yet east and west are not like that? If we are surrounded by an ice lining at the edges why don't we have photographs of that, flight is real and vehicles definitely have gone hundreds of miles high, shouldn't we have photographs?

Shouldn't a lot of ships, sailing in any direction have travelled enough to reach this boundary? And just how deep is this flat earth? It certainly has to be quite thick or else the weight of the water in the oceans would have blasted through by now. And most of all just where is this flat earth we live on stationed? Is it the only flat earth? If there are others why can't we see them.

Remember this dome makes all space flights a lie, so we might have gone to the moon or we might go to the sun, but anything out of this dome is impossible. So all the probes to Mars, Venus, Jupiter and beyond have to be fake.

And that my friend is how my mind works on days I have nothing much to do, I still think the earth is round though.

In this concept the North pole is in the center and Antartica surrounds the Earth. Beats me how they came up with this idea. But you can see what I said if you sail or fly far enough you will reach the edge and I have never heard of anyone reaching it.
