Extensive tests were made to see if animals have a language, just for information, I am studying linguistics in University and also have to look at non-human forms of communication. So far, no scientist found an animals that does speak a language, there are some apes that have a rather complex communication, but it only enables them to warn others of predators, like snakes.
There is nothing that shows they are able of complex thoughts, and many of their communicative capabilities are genetically preprogrammed. Indeed, Bonobos (dwarf chimpanzes) are able to remember things and even think ahead (to some extend). Those are the smartest animals around, but still their thoughts do not go beyond the basic needs (food, sex, place to sleep).
Go ahead and make a study on animals, show that they speak and think, that they are able to build up complex thought structures. As it is, the areas of the brain that are needed for language are nearly non existant in apes, and even less existant in other animals, so that could be a little problem.
I do think that an animal that only thinks about the most basic needs, without possesing more capacity for thoughts, and even lacking a concept of death, does not have a god.
And if you do not believe in what scientist say... at least they know what they are talking about, contrary to you, who only has unsupported assumptions.
