Deficiencies of Atheism I explained this already--how something can exist even though it's neutral or even disadvantageous for survival (not that I'm claiming this about anything in particular, just to stave off you reading it that way). So I'd just be repeating the explanation of that I gave earlier.
Are you absolutely sure? In other words you have explained hat it's just an additional feature but could not explain why?
Let me try to paraphrase, if you are explaining that mathematical abstract's are not required for survival in the jungle, then I'm missing your explanation as to why we have those attributes?
Surely you're not suggesting that someone should run calculations before they attempt to avoid a falling object, right?
Now what about the question of love? Can you explain that human phenomenon to me, or simply state what is, in layman terms?
If it's too complex of a subject here, I'll be happy to debate it directly with you in another thread. But for some reason I have not understood your logic associated with the concept of love...
For clarity, I summarize the two questions for you:
1. What is love?
2. Why do we have mathematical ability?
