Evidence God Exists

[Violet]

Communication of ideas is what I said. That's quite different. i.e. You can teach a man/woman to fish without him/her ever seeing water. I quite agree that simple communication is common throughout the animal kingdom. But simple communication isn't what I meant. We are able to share our thoughts, not just our 'feelings'. And not just in written form.
I don't understand nihilistic existentialism myself. Feel free to sum up for a simpleton..

Prairie dogs communicate ideas. Using language no less. Example link: http://www.petroglyphsnm.org/wildsides/pdlanguage.html

As for nihilistic existentialism... do you understand subjectivity? If so you're pretty much already there, just follow the logic through to its conclusions.
