How do we know that there wasn’t an intelligent species living here on earth before humans?
In: Earth Science
We don’t know. Like we don’t “know” anything in science. Science never “knows” anything, but rather builds models upon the most rigirious research and the available data. The extend to which we know there wasn’t an intelligent species here before us is that we don’t have any evidence that would point in that direction. And if you don’t have any evidence suggesting anything, its pointless to consider.
