Proof: Suppose that a=b. Then
a = b
a^2 = ab
a^2 - b^2 = ab - b^2
(a + b)(a - b) = b(a - b)
a + b = b
a = 0
What do you think?

I don't mean just any life, we know there's microbe based life out there. That's a long way from thinking the earth was flat and the stars revolved around us.

Do you think there's Intelligent life out there? If not, bring the variable of time in the equation. Do you think there was other intelligent life at one time before we existed? Or maybe there will be other intelligent life after the human species dies off?
