DDO Tier Tournament 2-Flat Earth Theory vs Spherical Earth Theory

Wylted
Romanii

Pro will be providing evidence for Flat Earth Theory. Con will be provided evidence of a round Earth. The debate should be determined by preponderance of evidence.There are to be no semantics with the terms round Earth or flat Earth. Neither round Earth theory or Flat Earth theory doubt topographical differences.First round is for acceptance. P.s. Romanii wanted me to add this. Round earth theory doesn't necessarily mean a perfect sphere. Just like flat Earth theory wo...

You may not claim the same animal as me.Once we have selected our animals (R1) we will use the succeeding rounds to debate which one is "better" where the criteria for what is "better" are: (a) appeal a...

PrefaceThis debate arose out of a discussion in the forums; the resolution is the same as the title of the debate.

The Planet Earth will eventually end

Mister_Man
Aerogant

I saw this earlier and found it really interesting, and was hoping someone would challenge my point of view, which is that Earth will end one day.Anyway, first round can be for acceptance or clarifying terms or even your beginning arguments if you wish.Earth - This should be obvious, but we are referring to the planet we currently live on, 3rd rock from the sun.End - Cease to exist. Not just uninhabitable, but completely...
