The reason why humans know the Earth is not flat are multitudinous.

  • Images from space
  • GPS
  • Currents and weather systems
  • Migration patterns
  • Observations of other planets
  • etc


Whether or not Earth is spherical in nature is a scientific question. One can prove that the Earth is round. Whether or not God exists is not a scientific question. You can neither prove nor disprove God exists. Being open to multiple possibilities is not in itself scientific.
If your only criterion for objective knowledge is science, then gwahir is broadly correct: there are thinkable unfalsifiable concepts for explaining science to be wrong on the matter of the earth being flat e.g. our perceptions are all edited by some higher being.
so the question is: is there a distinction between the concept of the existence of God and other unfalsifiable concepts? i.e. are there alternative sources of knowledge which point to God? Hence c1 and c2.
