You stating he used "elementary math" is certainly an opinion. Yes, math was used, but not the 1+1=2 math that you are saying. In any event that wasn't necessarily what I was stating as an opinion anyways. You saying that there is definitely not Aliens out there and they don't exist is what I was saying was your opinion (which it is). Thought that was obvious, but anyways.
Humans also didn't exist, until one day they did.
