Your point is non-sequitor, specifically a false reductio ad absurdam.
because a dog brain=/=human brain.
however,
iron=iron
carbon=carbon
mass=mass
mass has gravity
But Jupiter =/= Earth. My analogy is a valid one.
the power of the brain is related to structure, not the fact that it has neurons, which is certainly true of your dog and you.
however the roundness of a planet is due to what its made of.
In FE, the Earth is not a planet. And asteroids are made of the same things as planets, right? Why aren't they round?
asteroids=/=planet=satellite
Planet:mass large enough that gravity collapses itself into a sphere like object
In an illogical way yes it is valid.
unfortunately it is a false reductio ad absurdam. just because we can assume the composition of juipiter,
doesn't mean we can assume the ability of a dogs brain to equal human brain.
On a logical level, the brains ability is based on structure, not the inclusion of neurons. therefore the premise of dog's having a brain doesn't yield the ability to play chess.
The property of bodies to become a planet, however is based on inclusion of matter and size. therefore the fact that earth is made of matter like Jupiter, and is really big, bigger than venus (another planet), we can conclude Earth to be infact a planet.
On a scientific level, we have found that dogs cannot play chess, but people can.
And we have found Earth and Juipiter to be planets, and composed of matter
