Do you believe that there were full-size horses (over, say 50 inches tall) 50 million years ago? If not, then didn't the horse "evolve"? And if so, then are there any 50 million year old full-size horse fossils? Why not? (Perhaps the Earth isn't 50 million years old?)
Why all these questions? I already answered you on evolution by virtue of my mention of llamas and camels. What I do not believe is the Darwinian explanation.
To end the discussion I will answer your last questions definitively
