Our technology and our mental abilities are a product of our evolved/mutated genes...by this thinking we are VASTLY more 'successful' than any other species in existence.
Our sentience, and our ability to adapt, teach, share, trade and invent is astounding.
The world could fall into ice age, and if we have the time to make it work, we could build bio spheres and shelters that would keep many of us alive--yes, a lot would die, but we would still live on. Other species would not be able to survive unless ice was their habitat.
Also, there isn't a single species that could kill me if I had a machine gun. Again, our technology is an extension of our evolution.
There are amazing designs out there, alligator, mosquito, etc...but our minds surpass all of that. Our mind is the peak evolutionary route that mutation has taken. Currently, the human mind (and its sentience) is the most profound thing evolution has given the known Universe.
You can't do a human vs. dinosaur argument...time has changed, and so has our species. We would survive though...there's no doubt about it--as long as you don't use an overweight midwesterner as a sample.
lol.
