I couldn't tell you about the future because one day we may be able to have an impact on something that our generation couldn't even conceive of but everything up until the present is fairly insignificant as we've only had an impact on Earth and maybe we've made our presence known with the Arecibo message, though that's extremely unlikely and we wouldn't get a response in 800+ years assuming that sentient aliens with the similar technological capabilities exist around alpha Ursa Minor. So far we don't really have a significant impact universally but we may in distant future.
