Science is something in which all humans have always engaged. It is not necessarily rigorous science, but it is science nevertheless. Some 245,000ya, the first human that picked up a stone and threw it at a bird was performing science, and the bird itself in flight was also performing science. Many, many living things accumulate knowledge in the form of testable predictions, iow, a lot of things, all humans included, perform actual legitimate science. Whether or not these ordinary everyday scientific pursuits advance cumulative scientific knowledge is another question.
