This type of question cannot really be split into right and wrong. The answer will be different to each of us... it's "subjective."
I'd suggest it goes much farther back than humans. First science was that first cell that swam for food and tested the "object" near it by "eating" it.
Or, you could argue some "big bang" creation story which ultimately evolved into science as we know it.
However, I suppose a more common approach would be to argue something like Ancient Egypt or Mayan cultures and how they practiced changing their local environment and shared knowledge.
Not too sure though. If you feel strongly that the beginning of science is our mind... our knowledge, perhaps you can share more about your thoughts on that. There is nothing wrong with this answer, but it would be nice to hear more about why you chose that, and we can take it from there.
There are a lot of helpful and insightful people here, so don't be shy.
