You spag around and annoy the crap out of everybody and then start up a thread asking for a clean slate. Freeky asks you a legit question about your position, and then you start acting like a moron again. It gets suggested that you're being dumb on purpose, maybe trolling, by a couple of people. You don't help that perception by asking, "well what if I am" and go on to say that you started this thread being retarded so you may as well continue to be retarded in this thread. That's not how that works.
If you want us to take you seriously:
1) Don't troll us
2) Don't willfully ignore valid points for the purposes of stubbornly sticking to a position
3) Don't start acting retarded again when you said you were going to stop
Now, on the chance that you don't get what's being said here, by like, everyone
A) Arguing that humanity would go extinct without advanced intelligence is a pointless speculation, since that is a defining human trait
B) Even if you want to discount that and speculate, intelligence is not our only defining adaption, and not the only thing that kept us from going extinct. It caused us to flourish, no doubt.
Consider. I mentioned early humans instinctually making tools, without thought, without innovation, but out of compulsion. You said something about early humans and monkeys banging rocks about but not really using them as tools. But tool use is a common higher primate trait. They don't think about it. They don't set out to create it. They just make it and use it. Like a chimpanzee eating termites. The chimp just knows to poke a stick in there. Early humans banged rocks together until they made stone axes, and then they used them. These were not terribly imaginative people yet. So, tool making and tool use does not require higher intelligence on the order that we have now.
It does require hands and upper body strength, which again, is common to higher primates. It also requires the ability to walk on two feet, at least for a certain amount of time. Hominids excel at that. Even the dumb ones.
We are extremely well adapted to hot climates. Hominids are actually the best at that. We're able to remain active at temperatures over 100F for the whole day (please to see slavery as proof). It sucks, but it won't kill us. It will kill any other land animal. Even other African species. Way back, it was hotter than it is now. And we would hunt under the noon day sun, when other animals were trying to stay still so that they wouldn't die of exhaustion. Sure we had pointy sticks and those sharp rocks that we banged together, but that was really just overkill. You could just keep scaring your food until it had a heart attack. And other predators will run away from a small band of hairless apes chasing after it unless it no longer has a choice. So your tiger just had a heart attack too. Your dismissal of endurance not being special is stretches credulity. Human endurance is unprecedented. And we're stubborn bastards. This endurance is afforded to us through sweat glands, lack of hair, energy efficiency, and again, bipedalism. None of these things are intelligence.
Binocular and color vision- makes us a superior hunter. While binocular vision is not unique, color vision is rarer.
Omnivorous diet- no gazelle? That's ok. Here's a fruit tree. Or a tarantula. Whatever. No gazelle= dead lion. No intelligence required.
Scientists think our ancestors almost went extinct 1 million years ago, back when they weren't too smart. They didn't.
They also think that our species specifically came even closer to extinction 70000 ago as a result of natural disaster and climate change. But, hey, here we are, communicating across an ocean with our magic boxes. Maybe intelligence factored into it, maybe it didn't.
Also, there are dumber, weaker primates than us, like actual monkeys. They're doing alright on their own without much intelligence or superior strength.
There are plenty of reasons to shit on our species, but the reasons you give- weakness, inability to survive without intelligence, are most likely false. Intelligence gives us civilization, not survival. Sure, we're weaponized apes. But we're weaponized apes that can kick back and have a beer. A lemur can't but he's still alive.
Also, nothing would ever take our place. Like it or not, we are special. This planet is 5 billion years old and we only emerged in the last several thousand. In all that time evolution couldn't stumble upon us. And Earth is uninhabitable in about a billion years. We're not a repeat fluke. Certainly not whales who seem quite content staying in the water.
