"Earth-like" my arse!
orbiting a red dwarf star
tidally locked to Gliese 581
scorching heat of the sunward side
entire atmosphere frozen on the night side
Another fact is, with new technology ramping up, planets orbiting similar stars with similar orbits as earth are being discovered and cataloged...In the coming months and years, there will be tens of thousands more discovered.
The flat earth folks, will likely be spending all their time attempting to discredit each and everyone.
