Fiction vs History

[Keith McMullen]

 >>>When did human verification become the measure of " reality/ 
existance" .  Was the sub-microscopic world nonexistant before 
Leuwonhoek?  .  All the nonhuman species of the planet verify the 
reality of photosynthesis every day by eating and breathing, and trees 
need no chemistry lessons to carry it out.  Big brains can be fun, but 
are they fundamental even to consciousness ?<<<

Everything you assert in the above sentences is the product of human 
consciousness.

Sub-microscopic?

Photosynthesis?

Tree?

Chemistry?

Brains?

Consciousness?

Every one a human conceptualization.
