I'm playing around with a few ideas here. I wish I'd taken Latin instead of the four years of Spanish my family convinced me to take. I digress. I want to know how to translate the following ideas into Latin in the pithiest ways possible so as to echo the famous "Cogito ergo sum." I realize it won't sound exactly the same, but I'd like to at least know what I'm looking at. Any further suggestions are more than welcome. Thanks!
I think therefore god does not exist.
