He doesn't need to. He was explaining animals that do use tools and throw rocks in response to your claims that only bigfoot do these things. You are yet to provide any image of bigfoot doing it. Hell, you are yet to provide even credible photos of bigfoot. Just as you are yet to provide evidence, such as DNA samples to show that it is a new species of hominid or primate. Even your own so called evidence that you tried to rely on stated that the lack of any scientific evidence meant it did not exist. Ah the trees.. Yes, apparently bigfoot is so strong, that it is pushing these huge trees over in the forest. But it bangs on a cabin wall and doesn't break it or even dent it. Ya, sounds credible. You have no proof that bigfoot has done any of these things. All you have are accounts of dubious people who are making a lot of money preying on gullible individuals. Yes, because people are not going to do any of that to trick a bunch of people who are paying to search for bigfoot.. If we can detect and monitor secretive tribes that have never had contact with the outside world in the middle of the Amazon Forest, I am fairly certain that finding some hairy apes that "emit foul smells" and vocalise like apes and are strong enough to push huge trees over with their bare hands would not go unnoticed. And yet they don't dig up the dead bigfoot and take samples for testing? Nor do they lead scientists to these sites later on? How totally expected, because if they did so, then it would be actual scientific proof. But they don't because they know it is fake.
