How to introduce humans?

How to explain who humans are as a race? This is the most difficult question in this course so far, especially nowadays when a lot of things we were taken for granted as signs of development are questioned. While we can be proud of a lot of acheivements in the past centuries, there are far too many things to be ashamed of. I paraphrased the question to "how to convince an alien race that humans are worth saving rather than eradicating".

I've just read an article soemwhere that claimed the first trepanation, the first brain surgery in current terms is the moment of humans becoming an inteligent race. And we may find an answer there. Humans are caring. The human baby has a very long period of dependency on parental support, and cannot survive on its own. There are species, for example kangaroos for whom it takes very long to become independent, but they more or less still survive on their own. Caring for children is for the future, but humans also care for the elderly, very often without any utilitarian drive, out of pure altruism. And this is also quite unique. If humans didn't kill each other without any understandable reasons, both legally and illegally, I would put this as a main characteristic.

Humans are an interesting species who are very often ready to do things that are bad for them, and they do it understanding the consequences. This is also unique, but definitely wouldn't make us attractive. Our body has developed in a way that makes it suitable for using tools, but as a result of evolution at the moment we are unable to operate without such tools. This might be an interesting feature, a race fully dependent on limbs that are artificial, be it a screwdriver, a bicycle or even clothes as our fur disappeared and cannot protect us from the weather. At the same time, this is what made humans innovative and will eventually lead us to meeting aliens: making artificial limbs better and better. To aim for more with a body capable of so little, but with a brain that is more or less limitless in inventing new things.

And this leads me to answering the second part of the question. I would somehow humbly let aliens know how little we are capable of as long as we are left to our own devices, meaning the body, and showing them how far we could go with using our brain and inventing these "artificial limbs" to take us far and do it fast.
