> If there are two apples on the ground, and two more fall of a tree, then there are four apples on the ground. This is true whether or not a human is there to observe it and count them.

I don't know about that. How close do the apples have to be to number them? If two apples are within inches and another a mile away, is there two apples or three apples? Define ground. Is it dirt? And dirt of what? If two apples are on Earth and one apple on Mars, is there two or three apples on the ground? What does it even mean to number things? What is a number?

My point is that it takes a human brain for establishing definitions, axioms, and conditions. Only after these have been established can we do math.
