Sure why not
. Do you also have proof that animals do not have the "cognitive ability" to believe, Do you have proof that belief even has anything to do with cognitive ability? If there's one thing I learned from math(other than what an enormous headache it is) it's that when you get down to the nitty gritty pretty much everything we hold to be true or not true, real or not real, etc. is based on assumptions. The statement "if A=B and B=C then A=C" is considered a true statement. Is this statment logical? Yes. Is it provable or has it been proven? No (if it has then please provide the proof). Following this line of thought one realizes that just about everyhting(some would argue yes, everything) is based on faith. Even a statment as simple as "that's a rock" could be considered a faith based statment . After all could you really proof that the object is in fact a rock. All your senses may tell you it is but how do you know your aren't experiencing some sort of illusion, how do you know your senses aren't being fooled? All scientific scrutiny might tell you it's a rock but how do you know the scrutiny isn't flawed? Now granted if my senses tell me it's a rock then unless evidence is presented to the contrary I'll accept that it is a rock. My point is that there is a great deal of "truth" that is faith based(because there is no proof behind it), more than most(if not all) people realize.
