False.

Crows for example understand geometry. I’d wager there are plenty more.

“ These geometrical concepts do not exist in nature. There are no lines and squares. If it's obvious then why did it take 4.5 billion years since the development of life to emerge?”

What makes you think lines and squares don’t exist in nature? And what on earth does that have to do with how long life took to emerge?!

I would've also appreciated a discussion of how intuition of geometry might apply to chess playing abilities and how it might not be sufficient for playing chess well.

As a side note, I appreciated the small typos as a further signal that this was written by a human.

Not sure if he just recognizes the shapes as they appear or tries to make them appear, would be nice if he came here to answer.
